People file reports, but since mods of this comm are AWOL, we lemmy.ml admins—who don’t know anime/manga from a hole in the ground—have to respond to them. We don’t have the time or inclination to research the veracity of lilo/pedo/CSAM/whatever claims.
In that case, I suggest you shut down the community. At this point the core userbase and mods have moved to another location and this community only serves to confuse noobs and casuals.
I don’t blame you for not wanting to research the veracity of pedo claims, but this is within your control as admins. If you have a community that is unmoderated and frequently taking up admin time and resources, simply shut it down.
