Because the matter is in doubt. Read the rules you agreed to when you made all three of your accounts.
We don't get many circumstances "similar to this crap".
Thankfully the number of people we encounter that actually look to be lying about something as basic as their name is stunningly small. The reason we asked for your licence is because you, rather brilliantly, made it part of your username when that was the only part of your application for membership that is used as an identifier in every post as , as such, is required to be a true representation of your identity.
It's not my fault you did that.
We do check peoples names etc all the time - you might even remember as long ago as yesterday when we used it to discover you had the previous account you are now using.
Congratulations.
We are not persecuting you we are asking you to provide information. You are refusing to do so apparently.
You are entitled to your opinion. If it were myself getting banned from forums all over the place I would start to wonder where the blame really lay - what could be the common element in you versus all the snake forums?
I honestly bear you no ill will but if you cannot or will not comply with the rules you agreed to then, yes, your account will be banned.
