I am also not seen to offend other users.
Offending and cursing at others is not a bannable offense.
Not seen in the dissemination of false information.
You can lie and spread misinformation. The admins won't verify what is true and what is false, so you won't get banned for that either.
Not seen in multi-accounts.
Owning multiple accounts is allowed unless one of your accounts is or gets banned. In that case, all your accounts will be banned. You are also not allowed to enroll multiple accounts in the same bounties/signature campaigns, but I don't know if that is a bannable offence or just gets you a negative tag by DT members.
Considering that the posts Xal0lex found were written 5-6 years ago, maybe the admins will consider a 1-2 years signature ban instead of a permanent one. But if the number of posts is significant and there is also plagiarism in more recent posts, you are out of luck and the decision might be final.
