For now it has just gotten a decent amount of attention in bulk. It’s notable, but currently it’s best to wait for how long this’ll stay something. “Offensive” topics Social Justice Bloggers and the like spend time on come and go. Molestia is based on dark humor, and her concept goes back years, yet it’s only recent that it had gotten attention from this point of view.
For any coverage on the site, for now I’d consider a section in the Trollestia / Molestia / Tyrant Celestia entry. That thing needs a rewrite anyway, as it only describes the characters, but doesn’t show where and through what they spread.
As for this case, it’s something to wait and see first. The person who started it all seems to be very ill informed. The Ask Princess Molestia Tumblr is what started the case, which is a widely popular Tumblr within the brony fandom. However, the Tumblr also covers a side-story of Gamer Luna, which doesn’t have the same “Molesting” nature as the Molestia comics, it follows Luna being a gamer. People who’d follow the Tumblr would be easily aware of those comics, yet the person who started the whole cause seemed to be completely oblivious to it, as shown below:
So yeah, to call that Tumblr blog the cause is a 50/50. Currently that Tumblr seems more like the Scapegoat those on the “Stop Molestia” side needed. It’s a widely popular Tumblr, so of course you’d reach a wide audience by attacking that one instead of a barely popular blog.
