As i was told by the moderator I know on this site - and what I am going to write is not a secret, it's already known by all of you - Turnoi asked for all his posts to be deleted the first time some two years ago; the mods had to delete something like 10,000 posts on many boards (of course, the software does that). I feel that nobody cared at the ESLTB (most posts were a variation on the theme of "crap school") except for the editor who thought that it left most of the threads technically dislocated, with some posts left hanging ("orphan" i.e. a post is answering something that no longer exists). But he allowed Turnoi to re-start posting a few months later. Then, last February, Turnoi asked again for all his posts to be deleted. Again, I feel that nobody cared but it - again - left a lot of threads dislocated and posts hanging. I know that the editor told the mods not to let him post again for that reason.
A good account, thank you Fifi. SB made a good answer to the same question too.

It suddenly dawned on me as I was reading your post. Turnoi and his devilish assistant are doing all this at this moment because of sheer boredom, they have nothing to do now that the site is closed (as it can be) to them. I spose even the e-mail to me are timed, like timed when I am still half a sleep, and the first thing I see still rubbing my eyes is "Hi Wanker!" hahaha. he is a card that Turnoi. Well, a card and a half with his little helper.
