sexual assault allegations came up on the founder Evilore who took days to respond, in the meantime people started leaving, the site went down for day or a few days I forget... and that pretty well capped off the complete exodus
ERA came up as the reboot, and GAF pretty well bifurcated between itself and ERA, to which GAF is a deadzone that gradually built up into an alt-right hellhole, and the rest migrated to ERA which has become pretty sterile with a severe ban-happy trigger finger
This is pretty accurate
GAF is worse but ERA is also bad. Board 8 continues to remain the superior message board option
