REPORT OF DR. GOLBECK IN SUPPORT OF
PLAINTIFFS’ MOTION FOR CLASS CERTIFICATION
C 13-05996 PJH (MEJ)

10.

A copy of my full curriculum vitae is attached as Exhibit A to this report. I am

2

being compensated at the rate of $400 per hour for my services in this matter, and payment is not

3

contingent on the outcome of this proceeding.

METHODOLOGY AND SUMMARY OF CONCLUSIONS
11.

I am submitting this report on behalf of the Plaintiffs. I have been retained as a

6

technical expert to study and provide my opinions regarding the topics discussed in paragraph 16

7

below. My opinions, as well as the evidence I rely upon to support them, are set forth in detail in

8

this report. The contents of the various exhibits that I identify by name are meant to be

9

incorporated, in their entirety, by such reference.

10

12.

In preparing this report, I have employed methods and analyses of a type

11

reasonably relied upon by experts in my field in forming opinions or inferences on the subject.

12

The opinions expressed are based upon a reasonable degree of computer science certainty.

13

13.

Between now and such time that I may be asked to testify before the Court, I

14

expect to continue my review, evaluation, and analysis of information generated during

15

discovery, as well as of relevant evidence presented before and/or at trial. I also expect to review

16

the reports submitted by Facebook’s experts. I reserve the right to amend or supplement this

17

report, as necessary and as acceptable to the Court. I also reserve the right to develop materials

18

and exhibits as appropriate for use in helping to demonstrate and explain my opinions in the event

19

that I am asked to testify at trial.

20

14.

In forming my opinions, I have reviewed source code which I understand was

21

provided by Facebook’s counsel and which was represented as containing the relevant source

22

code between some time in 2009 and December 2012.

23

15.

Additionally I have reviewed numerous internal Facebook documents produced in

24

this litigation, as well as certain public materials. The list of documents I have considered in

25

forming my opinions is attached to this report as Exhibit B.

26
27
28

16.

I have been asked by the Plaintiffs through their counsel to opine on the following

issues:
a.

The structure and function of Facebook’s messaging system;
-3-

b.

2

Facebook’s interception of Private Message content, including:
i.

Whether and what devices Facebook employs to intercept message

4

ii.

Whether the interceptions occurred in transit;

5

iii.

Whether the interception of Private Message content was necessary

3

6

content;

for Facebook to deliver private messages;

7

c.

Facebook’s subsequent use of that Private Message content;

8

d.

Whether the class members can be readily determined based on Facebook’s

own records; and

10
11
12
13
14
15
16

e.

Whether the Facebook’s uniformly processed Private Messages during the

relevant period.
17.

Based on my review and analysis of Facebook’s source code as well as internal

Facebook documents and deposition testimony, I conclude the following:
a.

The structure and function of Facebook’s messaging system is described in

detail in Section III below;
b.

Facebook intercepted and redirected user’s Private Message content using

17

various code-based devices while the message was in transit, and this interception was not

18

necessary for Facebook to deliver private messages;

19

c.

Facebook used the intercepted Private Message content

20
21
22
23
24

as well as to increment the “Like” social plugin counter;
d.

The class members can be determined from Facebook’s own records using

various query methods and through self-identification; and
e.

Facebook’s source code operated consistently during the relevant period.

Overview of Facebook’s Private Message Architecture

An overview of Facebook’s Private Message architecture is useful. Say Alice is

sending a Private Message to Bob. In order to do so, Alice opens her Facebook message window

and begins to compose her message.

Facebook’s servers are the computers on which the Facebook system operates. They store code
and data, run the code, provide web content, and manage back-end functionality. Essentially,
every part of Facebook other than the code that runs in the user’s browser is running on Facebook
servers, and those servers provide every element of Facebook that a user interacts with.

The vast majority of web users have JavaScript enabled. In 2010, Yahoo!

4

engineers issued a report stating that 1-2% of traffic came from users without Javascript enabled.5

5

Those numbers appear to have remained relatively stable over time. A 2013 analysis showed

6

about 1% of users were not accessing JavaScript-based content.6 Thus, 98-99% of users have

7

JavaScript active and this Facebook code would run in their browsers.

Creation of Share Objects

Facebook has large and complex data behind its site. They store this in a data

19

model called TAO (The Associations and Objects).16 As the name suggests, there are two pieces

20

in this model: objects and associations.

21

33.

Objects represent things on Facebook – users, pages, checkins, comments,

22

locations, etc. Associations represent relationships between objects. Those could be friendships

23

between users, a like that connects a user to a page, or a location that is tied to a user check-in.

The Activity Feed plugin displays the most interesting recent
activity taking place on your site. Since the content is hosted by
Facebook, the plugin can display personalized content whether or
not the user has logged into your site. The activity feed displays
stories both when users like content on your site and when users
share content from your site back to Facebook. If a user is logged
into Facebook, the plugin will be personalized to highlight content
from their friends. If the user is logged out, the activity feed will
show recommendations from your site, and give the user the option
to log in to Facebook.

The plugin is filled with activity from the user’s friends. If there
isn’t enough friend activity to fill the plugin, it is backfilled with
recommendations. If you set the recommendations param to true,
the plugin is split in half, showing friends activity in the top half,
and recommendations in the bottom half. If there is not enough
friends activity to fill half of the plugin, it will include more
recommendations.

Users could also self-identify as class members. In anyone’s message inbox on

Facebook, they can go back and see their old messages. These will indicate if a URL

is present because it will have the URL and

THE CODE FOR ANALYZING PRIVATE MESSAGES OPERATED THE SAME
FOR ALL USERS
107.

As described above, I analyzed changes in the relevant portions of the Code over

16
the time period in question. The Code for analyzing private message

operated in the same

17
way for all users. If any Facebook user with a

VIII. “ORDINARY COURSE OF BUSINESS”
108.

I understand that Facebook asserts that the above-described processes are

22
employed in the “ordinary course of business.” I further understand that in the context of the
23
claims that Plaintiffs assert, an electronic communications service provider such as Facebook
24
“cannot simply adopt any revenue-generating practice and deem it “ordinary” by its own
25
subjective standard.” Campbell v. Facebook Inc., 77 F. Supp. 3d 836, 844 (N.D. Cal. 2014).
26
Instead, for an interception to fall within the scope of the defense there must be “some nexus
27
between the need to engage in the alleged interception and the subscriber’s ultimate business, that

“IN TRANSMISSION”
116.

I further understand that Facebook takes the position that the challenged practices

11

occurred “in storage,” as opposed to “in transmission,” and that they are therefore outside of the

12

scope of the statutes through which Plaintiffs bring their claims. My understanding is that an

13

interception must occur “contemporaneously with transmission” in order to have occurred under

14

either the Electronic Communications Privacy Act or the California Invasion of Privacy Act. In

15

re Carrier IQ, Inc., Consumer Privacy Litig., 78 F. Supp. 3d 1051, 1076 (N.D. Cal. 2015). As

16

described above, all the redirection,

19

117.

As the excerpt of the Adkins Deposition shows quoted in paragraph 30 above,52

20

the message is delivered when it is stored in the

message, and any URL

22

system. Until that point, the

As described above, all the processing of the message, including

delivered. Thus, in my opinion, Facebook’s interception and redirection of user’s Private

6

Message content happens while the message is in transit and not while it is in storage.
