Oh, I have...and never had a "name" for them before...
usually they are called "trolls", but then when you look at their home page...they are freepers for like 4-5 years!!!
NOW...I know...and you are a genius for the name you gave that group...
It wasn't original with me...I stole it from someone who stole it from someone else. I do think it's a good name for them, though.
