The people that constantly report spam the new channels have nothing else to do other than be offended at what they don't like. There may be a case in the future where we add filtering measures to vet who's able to join, but that's for the future, maybe.
I don't want to give out channel links because these same people are going to go and repeat what they did to HQ and take even those down, so you'll have to rely on word of mouth to find those groups.
Here's a list of sites you could sauce your content from in the meantime:
Pixiv
Gelbooru (Disable the filters)
ATF
Baraag
There's probably more, so feel free to let us know of some decent sites to add here.
