Eh, I like the family concept, keeps them included though they have moved away. "BL Family" "BL Mafia"...
or something that reflects their tenure with the site, going to "Greylighter" or "Silverlighter" or even "Platinumlighter" which are kinda ghey but are more inline with our naming convention.
Of course, we could always just go into left field with "wanker" or "in rehab"
