Hello,
My friend got banned from bitcointalk.org for about a year ago and he had only browsed and read the forum for over a month before the ban.
He did not get any reason for the ban.

He sent mail to a e-mailadress that was mentioned when he tried to get he's account unlocked. Did not receive a reply

Here is a conversation that he has had with bitcointalk on facebook

Hello, it says on bitcointalk.org that I have gotten banned. I was on my vacation and logged in quite rarely during that time and did not do anything else than read posts. How is it possible that I get banned for no reason? And no answers from the mail adress is says that I should mail to

We have recently unemployed a number of moderators who were randomly banning certain people as an attack on the forum. Now we can recover the account if it is still of any use to you...

Sure, that is no problem. We do chare a small recovery fee though because of the large number of requests.

Is bitcointalk really charging 0.25BTC for unlocking account! That's approx $140 according to today's exchange ratio!
