I'm gonna go ahead and hazard a guess that the amount of work you made for the mods under your other three accounts caused them to permanently ban you from the Classifieds.
No, I think you got banned because you and your dad were sharing an account, both posting under it and lying about which one of you was dealing in the classifieds. It was compounded by the fact that you're underage (or at least, you were at the time), making for some extremely surprised INGO members who were trying to sell firearms and thought they were dealing legally. Then, when the mods tried to clean up the mess you made, you did the same exact thing a second time. Be honest here and don't pretend you don't understand what happened.
Of course, you could have just PM'ed the staff instead of making a public thread about it.
are you trying to get your posts up to 50 or what?Well, this is awkward.
