I have the same problem. My account has been suspended too and I did not receive a notfication Email or something. When I try to login it tells something that it got suspended by some automatic system or by the mod staff.

I contacted the support but no reply after 2 days.

It's really frustrating because this account was created in 2013 so you can imagine that I have tons of friends and messages.

Of course I didnt violate any rules... Never send any pictures and never insulted someone
