I saw this thread and decided I want to give it a shot
IMMORTAL OUTLAWZ - Multiple Madness turned me down for Immortal Emcees, which UA had joined, and told me these nobodies were recruiting as a joke.
Latin Kings - Rican's crew. Can't remember much about it.
Street Gangs United - A crew me and a few people, notably Crazywhiteboy1 (the dude who I stole GET THE MOTHERFUCKING MOP from), sat in for a while until Cash One made CSK.
Crime Scene Klique - Probably the biggest dickrider crew of all time. Bestmceva, Cash One, Me, H-Nigga, Crazywhiteboy1, Mayneak. The links were flying.
BLACKOUT CLIQUE - A crew that me, Rain Matrix and BAR SHOTZ were in as nobodies, led by ET CnS. Little things like feedback threads were developed here which I have still adopted today.
UnEtHiCaL Conduct - My self representing crew. A few guys joined, most notably Kw0n, who later returned to LB as an AC.
Two Smoking Barrels - Ran by Olde English, and a crew he was in when he won his GC titles. My "big break". Mikey DeNiro, Rain Matrix and quite a few other guys were in there. I think I made it to captain.
UTILITY SERVICE SQUAD - After 2smoking went down, I was looking for a mentor and Askari helped out. After a while, I asked to join USS and he sent the invite. The crew grew to be the best on the site, and I, despite being a rookie, rose up to become a leader with UA, Askari and RTK. After it went down, I brought it back twice more, getting it to second on the site behind #1 all time MFD.
(A few crews I didn't give a fuck about for a while)
DNA - I joined for a tiny bit. I don't remember much, but it's a long time crew so I wanted to mention it.
Lyrical Killaz - Got invited to the home of Killa Season, but I didn't stay for long.
Letsbeef Pricks - D Reppin had returned and was running the crew dope, but again I was more into hitting the forums than being a good member.
Classick At Rhyming - They were coming up and HVK was developing some big names. Me and HVK went way back, so I wanted in on the action. I joined as a multi acc in college, but it turned out to be pretty dead by then.
Spectacular Vernacular - I was invited as a leader, even though I wasn't the most active with battling. I represented the crew a little bit, but I wasn't the number 1 guy for representing at the time.
Legion of Doom - The original one. It was basically a DNA rebirth. We had some cool features like a HW title in the crew. We competed in the first ever Illmania too.
Elevation Station - A short lived elevation crew I created.
Dead Poet's Society - I wanted to pitch in with a smaller crew, and I knew Rhet was a cool guy so I picked his crew. In there, we brought guys like Grizz and Fiji Osa into the "mainstream" of LB. Later, when Rhet got big, the crew changed from an elevation crew to a "vet" crew, which I still hate.
RKO'd - A crew made randomly by me and OSKAR that somehow blew up over night...and went down just as quick.
Sick Writers - As Master Masai in a course I was doing, I wanted to join a low level crew. I joined SW, ran by MadVerbs, to do so. We had a rivalry with R3AL, which had Phenomonon and Blocc, both later ACs, as leaders.
Goon Squad - Despite hating everyone in it, Wigsplit convinced me to join. Me and sWORDz teamed up to win the last and crucial battle of Illmania 2.
Turnbull ACs - As Masai, I wanted to make my own kind of crew, that was away from the dudes who were too pussy to protest the ban of one of LB's most productive members. I eventually did it as Dave, and it's probably the longest I've been in a crew at a year and a half.
Chloroformers - It was always the idea to make a second crew of ACs once we had gotten big enough. Chloro has proven to be ridiculously successful so far, and really sets ACs aside as an original crew. Letum, ILL and Phe were going to make Chloroformers as a rival to ACs before I convinced them to join, so the name choice was a cool little throwback.
