Roberto Silva: If anything is absurd, it's the very last paragraph of yours.

I would like you to tell me why should a person returning to a site under a new account after having been banned be banned again if they publicly admit that they are the same person and at the same time they make it clear that they are intending to obey the rules of the site. I just don't get it. You would be punishing the person for showing good manners, when they could easily keep creating new and new accounts and acting the same as before?

And I believe you should get used to the fact that "Roberto Silva" is nothing but an account here, as well as "Pedro Martínez", "bumble" or whoever else. If the site owner decides to ban me from here, he is banning "Pedro Martínez", not the real me. He blocks the access of "Pedro Martínez" to BrainKing, he doesn't come to my house and take my computer away. By the way, would you be willing to spend hours or days by considering the evidence on whether two accounts are indeed used by the same person? It is probably not the case of BK, but at some websites the site admin could possibly face a lawsuit if they ban someone without justified reasons.

The bottom line is: you DO ban accounts, not people.
