>>120309>I think Caballo really shit the bed with deleting people mking fun of avatarfagsThat wasn't why those posts were deleted. It was discussed multiple times in the public room and /meta/.
It was deleted because it was considered by some mods to be spam (literally repeating each post in a thread verbatim with an image attached, derailing many threads), but others felt that should be accepted on /b/ (within reason) as a meme or protest, interpreting /b/ as a more chaotic 4chan /b/ than a general discussion board. It was never to do with them being avatarfags, that's simply where the repost spam was because they were the most fun to annoy.
It's also worth noticing that some (certainly not all) of the spam at that time was actually from hostile non-leftypol.org users, including soyjak.party explicitly targeting a user. That doesn't excuse it, but it adds context to why it was treated as hostile against the site; some of it was.
