How do i know? You're the one who brought up the subject of being banned. I simply made the point that if you re-registered with a new username, you would effectively not be the person who was banned. You would be a new forum user to all intents and purposes.
When someone is banned, all that person's posts are deleted - it's as if that persona never existed.
I fail to see the logic in joining a forum on the basis that you can return as an alias if banned.
Why join in the first place if you feel you may be banned, also how do you know it is possible to return here. I am of the opinion that you have been banned from this forum before.
