I got an email from ero advertising today saying:

Plaintiff Facebook, Inc brings suit to enjoin ongoing infringement of the famous FACEBOOK trademark to promote an online adult network service.

In case you're promoting anything that violates the Facebook trademark, EroAdvertising is requesting a immediate removal of these ads from our ad network.

Thank you for your cooperation and understanding.
Sounds like the end of Facebook style popup ads.

Anyone using these style ads? I tried once for a couple of months, but they did not work at all for me.
