The warnings were about making personal insults which previously, along with others, he did. But that is not what he was banned for. The rules were changed after the event to snare Osvaldorama.
If posters didn't like what he was saying or how he said it, they could have ignored him but chose to reply often with insults. The so called wumming and baiting were described that way only because what he was saying was from a right wing perspective. Instead of ignoring him they couldn't resist trying to put him in his place. The playground boycott plan didn't work because there was always someone whose ego wouldn't let Os' comments go unchallenged. In my opinion, the mob played their part in the rows but instead of coping with a dissenting voice, they got him removed. It was always the aim, so job done.
The comment I made yesterday about banning posters was not because I want others thrown off (it's the opposite actually). It was about the inconsistencies around how it was implemented if we were going to have them. Yes there have been others who have had temporary bans but Os is the only one to have a permanent one, so yes he has been singled out.
