To clarify, I was thinking along the lines of a situation where someone might post a question and some of the replies are from ignored users (possibly mixed in with non-ignored users). If I wanted to answer the thread starter's question and I had a large ignore list, I could either choose to submit an answer with the risk that others might think that I am parroting what has already been said (which I'm sure most people wouldn't think too positively of) or read the ignored users' posts which kind of defeats the purpose of having an ignore list. It's not a huge problem if most of my list consisted of trolls since they're not likely to contribute intelligently to discussions but a much more comprehensive list that encompasses a wider variety of users could eventually cause problems.
I don't recognize any of the names in your list and it isn't very long so it's probably fine. DannyHamilton's list goes a bit too far in my opinion since it includes posters like redsn0w, bryant.coleman, and Muhammid Zakir who tend to make highly constructive posts and are an integral part of this community.
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.
