Can you post a screenshot of the red warning? I think you were permabanned, but I am not sure at 100%. As shorena said, you were banned mosst probable for the content of your posts and you should improve your quality. Now I suggest you to don't evade the ban and not post outside the meta section.

Oh, This is the first time I know how to post a picture here. Thanks for all you here !
Really strange, there isn't an email either a "period" so I can't say if it is a perma or limited ban. You should wait an admin, because we can't help you much here.
@UNBTC, did you buy the "soowein" account as well? Its possible it was banned before.
Its fine to log into any account you have, just dont send PMs or post until this is resolved as this might get the other account banned as well. I am not sure how staff handles perma bans for bought accounts, but probably the same as if you had been banned before. Can you tell us who you bought the account from? Maybe the person can answer whether the account was banned in the past.
