I, just like HongKongFoot, used to be a highly abusive poster. Then I realised that this was something I did when I knew I was wrong, and the other guy/gal made a point effectively against my argument(s), and when people misunderstood my posts (without considering that something may have been amiss in the way I originally expressed my views) or heck even if someone disagreed with me.
I also react a lot less to being called names these days.
Having said that, I am sure there is a policy in place whereby a member may be banned after being issued a bunch of warnings, and I would fully support that. I am not sure a poll would be the most effective way to get someone banned, because at the end of the day Shri owns this site and he gets to decide on banning members, regardless of how unpopular his decision may be.
Reporting a post may prompt the admins to fire off a warning to the poster, and I have, in the past, reported a post or two of HongKongFoot's to them for being unduly abusive simply because someone disagreed with him/her.
