Apparently APM was shut down because of a C&D from Hasbro. But the author was planning on ending it anyways, it just ended a little sooner than he intended.
He doesn't seem particularly upset about it, and I didn't really even care outside of "I do not want to read this" so yeah.
That being said, the actual rape jokes made by other bronies disturbs me.
The C&D resulted from the Down With Molestia folks outright e-mailing Hasbro's LEGAL TEAM and ranting about how the blog was nothing BUT rape jokes (which isn't true in the slightest) and that it was damaging their brand. Never mind that Hasbro hadn't really given a shit about Molestia, or any NUMBER of tumblrs that are even WORSE with actual sex and violence and rape and body horror (looking at you, Lil Miss Rarity, even though I read that too). But it was because of these whinebags actually taking it that far that the C&D even happened.
Yes, JJ finally said 'fuck it', but that really, really didn't do the anti folks any favors, considering they're literally cheering that they've "done away with getting rid of rape culture in the fandom". Yep.
