Yup, this is the exact same thing that Dolphin and the rest of his /cow/ niggers had done, except he tried shutting down various alt imageboards as a whole instead(if I recall he succeeded in doing so at least a few times). Then, he blamed anime posters/lolicons and other groups he didn't like for the very real CP he was spamming, and somehow he was celebrated as a hero on /cow/ for doing so, even getting a few imitators. This included raids on boards that tengu used as a retaliation for outing him being the main spammer during Julay's downfall, shortly after that happened.
Anyways, like I said, times change but these kinds of bad actors don't. I bet one of the groups will blame someone else they don't like for the spam to try and get them banned, while jannies are allowing the porn to stay up conveniently because it aligns with their interest. If there was a single anon left on 4chan that wasn't buck broken already, the moderation team would already be doxed at the very least for what they've done over the last few months alone.
