I myself only have two members on it. One is rather obvious if you've been around, and the other no one probably knows but was extremely rude to me for no reason over PM. So I chose to not have to deal with them any more. I'm pretty tolerant for stupidity since I am a derp. But apparently other members have many many many people on their list.
How many people are on your list? What does it take to make it onto your ignore list?
This is not an invitation to say WHO is on your list lol. That could get awkward.
