WTF ?! Facebook page limited !

Everything is in the title : don't know why my fb page has been limited. I didn't even know that was possible !! I only got 1400 likes one months ago using AddMeFast, then stopped doing that shit (to remain under the radars) and 2 days ago I received a message saying that all the likes related to my page are disable.
Does anybody faced the same issue ? I browse the forum for such a case but didn't find anything similar
Anyway : if that kind of limitation is common, buying likes or bots is a total waste of money and time...

Yes it seems alot of users that used social network exchange programs like addmefast, have had there pages restricted. Facebook are cracking down!
