This ruling is a new low and says more about you than Osvaldorama. Not only do you allow posters to break the rules with personal insults but join in too. Banning him because "he had ruined the level of debate" is a poor joke. There are more than one or two posters from the other camp that could be levied at but seem to escape sanction. If I have to read the level of debate that StJabbo and loading produce every single day then I'm sure you can all put up with Osvaldorama's efforts.
The level of debate is poor because you and others can't deal with conflicting, unpopular opinions. Despite what you and like minded posters may want the politics thread is not about a happy little clique looking for "consensus", it is (or should be) also about others having their say without being censored.
You all complain about him but you continually bait him into replying, even when he's not online. You talk about him constantly between yourselves, quite often with insults and piss takes. Nothing wrong with that but you can't then expect him to not reply, and in the same manner. And what he posts about is not up to you to decide.
In the last week alone, there have been 15 different posters who have made comments to Osvldorama or about him, a bit strange coming from those who want him ignored.
Banning him for his unpopular views is more childish than the pathetic boycott you tried a few weeks back.
