Just found about about the FiMFetch debacle.
Basically, the operator of an MLP fanfiction archive not only deleted all "foalcon" related stories from the archive, but also went on a moral crusade to call out as many people who create and/or consume this content as they could find.
Their definition of what counts as "foalcon" turned out to be incredibly broad, and includes aged up depictions, non-sexual stories that just happen to be marked as mature, and even artwork of adults that just happens to have the "younger" tag. (i.e. the elderly Granny Smith as a young mare)
At least one artist was put on the list, not because of anything they actually drew as most of their work is SFW, but because of NSFW edits of their artwork that they did not create.
And the cherry on top of this whole shitshow? A discord screenshot was leaked where this righteous moral crusader admitted to having, in their own words, "a weakness for Scootaloo" when sent an explicit image of the character.
Just want to make it clear that I don't like foalcon myself, and to be fair, some of the people on the list were also alleged groomers, and at least one person had actually been arrested by police for possession of CSEM (presumably REAL CSEM), but why am I not surprised that the person who went on a moral crusade against fictional smut turned out to be a projecting hypocrite with a taste for chicken?
EDIT: It has come to my attention that the artist in question has drawn some explicit works, none of which involve underage characters. They are still on the list because of an edit featuring their artwork, not because of anything they drew themselves.
