Are the images in these spam posts NSFW? Since I'm in a crowded classroom I can't really check (I saw one for a split second and it seemed questionable so I blocked images on the review queues for now)
If I had a nickel for every time somebody put NSFW images on a website related to CGCC, I'd have two nickels, which isn't a lot but it's weird that it happened twice.
@mathcat How certain are you that it was that? Could be worth reporting to NCMEC, not that they could do much but IIRC they control the hash lists that are used for detecting that stuff on file sharing/hosting sites
