I don't use it very often. But sometimes there are just people screaming for me to use it! LOL! I think some are gone. I haven't seen posts from them in quite a while. Right now I have 17 people on it, and I can think of two sitting on the edge about to go in.
I use it all the time. I have about 10 people on my ignore list and I add to it every day. Sad really. I think Walt Disney would be sickened that there are that many people on a board devoted to Disney that require the ignore button.
I used it once, for someone who was so annoyingly obnoxious that I couldn't stand to even see their name!
Haven't used it lately, although there are a couple of posters who tend to post on the political threads who are really getting a little over the edge with their wild ideas etc. Bordering on paranoia, if you know what I mean .
