My first thought was, why ADVFN only, why not iii etc?
wallstreetonline (the German board) abruptly closed its LGB threads some months ago, MonkeyFM hasn't had a post for a year, nothing on Motley Fool, iii (the secret board) seems dead. Conclusion, ADVFN is the only place where there is still active discussion and Rybak is trying for an injunction against the publication of any further libels, i.e. trying to close it down.
If that's correct, it will be a relief to those who thought he was a-comin to git yer!
With luck we'll get a report from someone who went and until then, not much point speculating on the WHY question. Obviously I might be totally wrong.
