Cushbomb and Felix were both LF posters, for example. LF was the most interesting place on the internet, spawning both the reddit woke movement with Shitredditsays and the dirtbag left with Chapo Trap House.

It started in 2007 or 2008 during the peak of internet libertarianism as a place to relegate Ron Paul supporters. But since it followed FYAD forum rules, anyone could go in and own the Ron Paul supporters. Eventually all but a few were driven out.

LF then turned into an ironic and not ironic space where people would try to one-up each other in leftism. There was also learning about critical theory type stuff going on during this, with popular threads about the writing of Deleuze. The forum turned to Maoism-Third Worldism, because although it may seem impractical, it is very consistent. From MTW there is a natural fork in the road to woke idpol insanity, or the also non-racist but not insane dirtbag left.

Eventually someone threatened to kill Barack Obama, and the forum was spammed with goatse and shut down.

A lot of good internet left stuff comes from LF. Chapo, @getfiscal, shitredditsays (for the brief time it was good), the rhizzone to name a few.
