ORDER GRANTING IN PART AND DENYING IN PART MOTION FOR CLASS CERTIFICATION

PHYLLIS J. HAMILTON, United States District Judge

On March 16, 2016, plaintiffs’ motion for class certification came on for hearing before this court. Plaintiffs Matthew Campbell and Michael Hurley (“plaintiffs”) appeared through their counsel, Michael Sobol, Hank Bates, David Rudolph, and Melissa Gardner. Defendant Faeebook, Inc. (“defendant” or “Facebook”) appeared through its counsel, Christopher Chorba, Joshua Jessen, Jeana Maute, and Priyanka Rajagopalan. Having read the papers filed in conjunction with the motion and carefully considered the arguments and the relevant legal authority, and good cause appearing, the court hereby rules as follows.

BACKGROUND

This is a privacy case involving the scanning of messages sent on Facebook’s social media website. Facebook describes itself as the “world’s largest social networking platform,” with approximately 1.2 billion users worldwide. Facebook users are able to share content — such as photos, text, and video— with other users. Users can select the group of people with whom they wish to share this content, and may choose to share certain information publicly (i.e., with all Facebook users), or may choose to share certain information only with their “friends” (i.e., Face-book users with whom they have mutually agreed to share content). Facebook users may also choose to share certain information privately, with just one other Facebook user, through the use of a “private message.” While not identical to email, a private message is analogous to email, in that it involves an electronic message sent from one user to one or more other users. Facebook users access their “messages” through an inbox on the Facebook website, akin to an email inbox. This suit arises out of Facebook’s handling of these “private messages.”

In the operative Consolidated Amended Class Action Complaint (“Complaint”), plaintiffs allege that Facebook scans the content of these private messages for use in connection with its “social plugin” functionality. The “social plugin” operates as follows: certain websites have a Faeebook “like” counter displayed on their web pages, which enables visitors of the page to see how many Faee-book users have either clicked a button indicating that they “like” the page, or have shared the page on Facebook. In essence, the “like” counter is a measure of the popularity of a web page.

Plaintiffs allege in the Complaint that Fa-cebook scans the content of their private messages, and if there is a link to a web page contained in that message, Faeebook treats it as a “like” of the page, and increases the page’s “like” counter by one. Plaintiffs further allege that Facebook uses this data re[256]*256garding “likes” to compile user profiles, which it then uses to deliver targeted advertising to its users. Plaintiffs allege that the messaging function is designed to allow users to communicate privately with other users, and that Facebook’s practice of scanning the content of these messages violates the federal Electronic Communications Privacy Act (“ECPA,” also referred to as the “Wiretap Act”), as well as California’s Invasion of Privacy Act (“CIPA”).

Plaintiffs now move for class certification, but their current class definition differs from the one set forth in the operative complaint. The Complaint is brought on behalf of “[a]ll natural-person Facebook users located within the United States who have sent or received private messages that included URLs in their content, from within two years before the filing of this action up through and including the date when Facebook ceased its practice,” Complaint, ¶ 59. In their motion, plaintiffs move for certification of the following class: “All natural-person Facebook users located within the United States who have sent, or received from a Facebook user, private messages that included URLs in their content (and from which Facebook generated a URL attachment), from within two years before the filing of this action up through the date of the certification of the class.”1 Dkt. 138 at 10-11. The key differences are (1) the inclusion of a parenthetical that limits the relevant messages to those “from which Fa-cebook generated a URL attachment,” and (2) the removal of the reference to Facebook ceasing the challenged practice.

At the hearing, the court questioned plaintiffs about the incongruity between the Complaint and the class certification motion, and plaintiffs’ counsel explained that the changes are the result of new information that was learned through discovery. And in addition to the changes to the class definition, plaintiffs’ motion also describes two additional ways in which Facebook allegedly violated the ECPA and CIPA, beyond the one alleged in the Complaint.

As mentioned above, plaintiffs’ original theory was that Facebook scans the users’ messages, and when a URL was included, it would increase the “Like” counter for that URL. Now, plaintiffs allege two other interceptions/uses2: (1) Facebook scans users’ messages, and when a URL is included, it uses that data to generate recommendations for other users3, and (2) Facebook scans the messages, and when a URL is included, it shares that data with third parties so that they can generate targeted recommendations.

[257]*257Plaintiffs’ motion (and accompanying expert report) describes these two newly-alleged practices, and also sets forth more detailed allegations regarding the “Like” counter increase. Plaintiffs’ motion makes clear that these new allegations are derived from a review of Facebook’s source code, which had not yet been produced at the time that the operative complaint was filed.

Plaintiffs explain that, when a Faeebook user composes a message with a URL in the message’s body, Faeebook generates a “URL preview,” consisting of a brief description of the website and a relevant image from the website, if available. Faeebook keeps a record of these “URL previews” — the record being called an “EntShare.” The “EntShare” is tied to the specific user who sent the message. Faeebook also creates another record called a “EntGlobalShare,” which tracks all users who sent a message containing the same URL.

Plaintiffs then specifically describe the three ways in which the message data is allegedly redirected and used. The first is to “fuel its algorithms for measuring user engagement and making recommendations.” This alleged use is related to the “EntShare” and the “EntGlobalShare” described above— essentially, Faeebook keeps a tally of the number of times that a certain URL has been shared in users’ messages (the “EntGlo-balShare” number), and then incorporates that number “into secret algorithms that pushed content to users across the social network.” As an example, plaintiffs cite to Facebook’s “Taste” system, which generates recommendations “to push to targeted users that Faeebook believes the user would find relevant.” The recommendations are generated by a piece of source code called “External-NodeRecommender,” which takes into account which URLs a users’ friends had shared (in other words, a user’s friends’ messages will be weighted more heavily than the messages of random users in generating recommendations). Thus, plaintiffs allege that “Facebook’s recommendation system used private message content to target Internet links to specific users.”
