Leftypol, afaik, has always been a glowop, and the government seem intent on crushing its support of Z and Gaza. Currently, the level of NAFO attack is increasingly high, and with an appropriate level of human, automated, and semi-automated attack, we could go under, especially since mods want it to collapse. How would you feel about an evac? I understand you do need to filter as Leftypol is very loosely moderated. And do you have plans if government troll farms go after you as well?
Ah, I wasn't even thinking about non-photo stuff. I don't know enough so I'll take your word on that one. They would definitely do their best to delete the photo stuff, because it's capitalist advertsiting, spam, disgusting to the point users would leave the site and also grounds for being reported to their server host. But I can't say I would be surprised whichever way they approached cartoon stuff, and I think it's reasonable to bring up 'chan culture' there.
I don't think the historical roots to 8chan are particularly relevant to this issue, because looking at 8/leftypol/ on the wayback archive, they explicitly had an anti-loli rule. It was just one board at the time rather than the collection it is now, so 8chan's notorious freeze peach US Libertarian liberalism didn't apply to /leftypol/ then.
I find that hard to argue, sharing a board with a website hosting actual CSAM (as well as q-anon shit and conspiracy up the ass) is a terrible look
8ch was the reddit of imageboards in more ways than one; reddit infamously hosted /r/jailbait and other horrible subreddits for many years. Socialist subreddits (incl. those which were historical roots of lemmygrad.ml) weren't really affected by reddit also having CSAM, fascist, etc. boards because one can completely ignore they exist elsewhere on the site. The same was how /leftypol/ was. And in both cases, the community was on a crappy site because it's free hosting, there's no implied common values.
