The scroll wheel on the mouse is my ignore button.
I hardly ever had someone on ignore since the start of me surfing the Internet.
It is better to see where the rascals are up to, than have to guess about it IMHO.
I rarely put people on ignore. People like Bubba, why bother. He's long gone too. There were two long time posters to SLU that really got under my skin and were pretty well liked. One no longer posts and the other has mellowed out so no one on ignore now.
