This is why I keep a strict list instead of a more wide one. I've often been accused that this is a "bear" list. I can assure you; it's not. The main problem with adding a person that:

a. Has a newbie account
b. Posts vague and/or irrelevant things
c. Kills his time

against a known sockpuppet account, is that's not always clear. As I've stated before, I constantly update this list and move people out of it if they follow my 3 over 3 rule (ie: 3 out of 3 posts are not trolling). It's not THE golden rule, but surely kicks some people like BlindMayorBitcorn out of this list as he posted constructively for 3 times in a row, no matter if he was rude and offended me in one of his previous ones.

Being provocative in a public forum is not tolerable. It feels safe, but it's not noble, nor sane. If you want to be provocative and offensive to someone, IMHO you should have the guts to look him in the eye when you do it and not from your couch comfort, behind a screen and a keyboard. Again, I'm not claiming the infallible. I know that someone can do this job better than me. If you're that specific someone, please make it happen and I will blindly follow.

As a side note, I'd judge your comment of the chance missing some post as a collateral damage. Nevertheless, if that poster follows my 3-3 rule he will be probably out of the list sooner than that happens.

Cheers.
