as some other anons have said like
>>694857 a few of the mods tried to coup the site since they were getting outvoted on policy (they called the majority of mods as "Caballo's clique" due to their supposed tendency to vote in line with the then-mod and now-site admin Caballo) and they thought the current mods were too strict since they wanted to talk about idpol and infrared stuff and "transhumanists" etc. Except they didn't control the domain so eventually the original mods took it back.
Essentially it was a disagreement about the level of moderation on the site that lead to an attempted coup which failed.
