Why my forum is deactivated?

My forum "Engineering House"
http://eng-house.yoo7.com

this is for Engineering students and there is any violent or porn contents.
suddenly, it was deactivated and I don't know the reason.
How can I reactivate it? and who can tell me the reason for deactivating it?

Please, I need a help quickly
Thanks for you

Did you tried to press contest this decison? You should dot that first and wait for reply.
Maybe your forum had warez(illegal software links, activations)?

Did you say you had porn on the forum? Because that would of answered your question.

If there wasn't any illegal content on the forum please click contest the ban. We don't have control over if it will come back since we don't own OnlineGuardian.net

I think the Original Poster meant to say there *isn't* instead of is. The sentence makes more sense.

Thanks to you very much
I sent contest message, but there isn't any reply

If there isn't any reply, it means it did not respect the TOS & they won't return back your forum.
