There was a time when my characters were more clothed than they are now, and, every time I drew anything at all, this one guy would send me a bunch of "can you post a shirtless version?" messages that all had the same typing quirks and also often had descriptions of two very specific shirtless outfits he was fixated on.

They got worse and worse and more and more frequent the more I ignored them, until eventually one day he sent like 15 nearly identical messages across 3 sites in the span of a few minutes, and the only way to make him stop was by completely disabling anon asks for a few months because anon blocks just didn't do anything. òHó

And if you've ever seen me draw a character with a neon "OPEN" sign on their shirt, it's because early on, before he got super extremely desperate, I intentionally misinterpreted one of his requests for a character wearing an open shirt because I always creatively misinterpreted anonymous art requests back then, and I somehow thought it would make him leave me alone. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ Anyway, now the shirt is a permanent part of all of my characters' wardrobes. :P

(Also, unrelated, but someone who was NOT Shirtless Anon and who'd never interacted with me in my life tried to cancel me for misinterpreting the "open" shirt request because Tumblr was hell. :D)
