I think he is usually just pulling random people (for the most part) from the thread to feature on his hate-boner page. However if I had to guess why this time...
You and I because Len can't help himself when he "sees duh gud lukin laydeez"(I think he may actually be that simple),
@Kirby because they've been a big part of this whole thing,
@AnOminous because Lenny's always thought they were part of the Lenspiracy and argued with Len back when he would post in his own thread, and
@ChurchOfGodBear because I dunno...they've never posted in this thread but maybe some coolguy told Len that user name at some point.
