tigger,
Your IP Addy is what is called dynamic.
That is::~
The 1st part(Country) stays the same
The 2nd Part(Your Internet Service Provider) say BT, AOL, TalK Talk, stays the same
However
The 3rd Part, the individual link from your PC to your ISP's server is different every time you log on.
So AB's server would not be able to recognise your IP as it's end numbers change every time.
Even more so if someone uses a different Internet cafe,or uses the Internet Service in a library for instance.
I do think that if AB trusts guys to be moderators,then they should have the power to remove posts,as at weekends this would mean troll posts could be dealt with quickly
If troll posts were removed quickly,then(possibly) such trolls might give up(for a while at least?).
The power of banning a poster should remain with the ED though.
