If I remember correctly @"BF3Dreadnaut" was having some bad times on the forum and he was in a similar position to what you are in now. He has turned it around people don't even seem to remember any more.
The community here is very strong and they take offence to people seeming to try and disrupt or cause problems.
The first thing you can do is stop talking about the past and just try and be a little more HQ in your posts and I am sure the members will forget about it.
