You may wish to look at these abusive** posters' multiple mbtu lists...and compare a few IPs while you're at it...this is not the entire list, but it's a start. Once you compare IPs, you'll probably be able to figure out who's who, anyhow. And I bet you've already got a pretty good idea, considering the history of these two:

Luno

Elan

Citizen Exile

The Odd Neighbor

Lapcat with underscore

Angle (no, not Angel)

Galatial (no, not Galatea)

Catcrapping

Cat [space] Napping

Cat [space times 8] Napping

HeadInjuryHaiku

(yet another) Head Injury Hiawatha

Horatio Cain

Jabberwocky

Jack [space] Dallas

cat E gory5

Barbed Why Her

**I picked these, because they've been stalking a few of us, and attacking. One of them visits my blog, regularly, and episodically leaves abusive posts. (If you ever wanna compare IPs, let me know.)
