Badspot has number one topic starter for awhile, than that time with RTB Mod Bot :P.
Badspot has a lot because of all the "MOVED:" topics.
I don't know if being on those lists is a good thing or a bad thing :/
It depends on how long they've been here.
You should really look at the posts per day instead to determine whether or not it's bad.
Someone who posted in 2005 could easily achieve that top 10 without being very active.
If someone who jioined in 2009 was in there, then that's really not a good thing.
