With Web hosting companies and financial services firms dropping support for WikiLeaks, what about the country's most popular social-networking site? For now, WikiLeaks will remain on Facebook because, the company said, it is not aware of any unlawful content.

"We haven't received any official requests to disable the Wikileaks page, or any notification that the articles posted on the page contain unlawful content," Facebook said in a statement. "If we did, of course, we would review the material according to our rules and standards, and take it down if appropriate."

In recent days, PayPal, MasterCard, Visa Europe, and Swiss bank PostFinance have dropped support for WikiLeaks for a variety of reasons, namely for hosting illegal content. The site has also had to switch Web hosting services several times.

For Facebook, however, "the mere existence of a WikiLeaks fan page on Facebook doesn't violate any law, and we would not take it down just like we don't take down other pages about controversial topics," Facebook said. "We're continuing to monitor the situation."

The WikiLeaks fan page currently has 1,087,178 members.

Similarly, WikiLeaks's Twitter page has remained intact, and has been a primary source of communication for the embattled site, in addition to Facebook. Earlier this week, Twitter denied that it was censoring mentions of WikiLeaks on its trending topics list.

UPDATE: Later in the day, however, Facebook did remove the page of "Anonymous" after the group orchestrated denial of service attacks against Visa and MasterCard in support of WikiLeaks.
