Why does Facebook scan private messages?

The answer is very simple, the company routinely scans private messages in order to prevent abuse, its engine search for malicious URLs or any link to child pornography and violent content. Anyway, Facebook is accused of using the data resulting from the scan for advertising and to target its offer.

The company defends itself against accusations, claiming that its systems scan users’ private messages in bulk, and keeps any extracted data in an anonymized way.

The plaintiffs sustain that Facebook is currently maintaining a database, dubbed Titan, it includes all the URL-related message alongside with metadata that could be used to track a specific user. Each record includes, for example, the date and time the message was sent, and the user IDs of both the sender and the recipient.

This isn’t the first time that Facebook is accused of threatening users’ privacy with its practices.

The CNET news portal reached the company for a comment on the case and below is reported the reply of a company spokesperson who confirmed they stopped any practice that exposes user’s privacy to serious risk.

“We agree with the court’s finding that the alleged conduct did not result in any actual harm and that it would be inappropriate to allow plaintiffs to seek damages on a class-wide basis,” a Facebook spokesperson told CNET. “The remaining claims relate to historical practices that are entirely lawful, and we look forward to resolving those claims on the merits.”

The position of the company is in contrast with the claims of the plaintiffs that sustain Facebook is still scanning private messages for commercial purposes violating users’ privacy.

“Facebook’s source code not only reveals that Facebook continues to acquire URL content from private messages, but that it also continues to make use of the content it acquires.”

The lawsuit was filed in 2012 and still have to be proceeded, the plaintiffs have until June 8 to file any amended complaints.
