Sens. Charles Schumer (NY), Michael Bennet (CO), Mark Begich (AK) and Al Franken (MN) are sending a letter urging Facebook to change its "opt out" policy to an "opt in," so users can avoid receiving unsolicited advertisements.
Aides say users can opt out, but the default is that their info is accessible to outside Web sites. The senators want Facebook to reverse that.
They are also complaining to the Federal Trade Commission.
*** UPDATE *** Facebook reached out to First Read for a response. "We appreciate the concerns raised by Sen. Schumer and expect that further dialogue with interested members of Congress about the user controls that accompany the tools announced by Facebook last week will alleviate any concerns they may have," said spokesman Andrew Noyes.
Facebook also wrote a blog post on the issue, trying to answer questions users might have and penned a letter to Schumer, in which it claims: "Facebook is a leader in transparency of our policies, notification to our users, and security of their data."
