Samael was a person who paid $1000 to Toby Fox to have his “fantroll” in Undertale with a boss fight, unique room, etc. He submitted a fat-fetish fursona instead, someone told Toby it was a fat-fetish porn character, and Toby offered to refund Samael’s $1000 so he wouldn’t have to put it in the game. Samael refused the refund, so Toby still put the character in the game, but made him a secret character–he still got the unique dialogue, room, battle, etc. Samael was upset about this and made a post about it and compared his character to Muffet (who Michelle designed) and said it wasn’t fair that Muffet got a more prominent role in the game while his character (So Sorry) was a secret character.

People jumped on this as an excuse to disparage Michelle more, saying that because Muffet’s clothes are “lolita” she’s a pedophile (and also because of the nude art she’s drawn).

Honestly, I would have just refunded Samael’s money without asking, and said that I wasn’t able to fulfill the obligations. Toby would have been well within his rights to do so. It’s been clear from the beginning that Toby has wanted to be careful about how his game is presented–he even asked that there be a specific tag for NSFW shit so that kids wouldn’t accidentally stumble upon porn that people would inevitably draw of his characters. He knew people would draw NSFW stuff, but that doesn’t mean he had to be comfortable with putting a fetish character in his game.
