what's the best way to deal with your prompts getting taken in ways you don't like but technically aren't derailing?

it feels like every time there's any response to one of my prompts, it manages to go in directions that I didn't rule out because it didn't even occur to me anyone would want that, that's the opposite of the point!!!

maybe I'm just out of step with the meme's culture or unnaturally picky and should just write more of my own stuff, but it's really frustrating. I don't want to swoop in as the fun-forbidding OP or shit on other people's prefs because YKINMKATO and all that, people are getting inspired and having fun and that's great, and it's not actually unrelated enough to my prompt to ask for reposting, but I also wish I could clarify what I want/like without feeling like a mean party pooper. Plus I feel a bit awkward just abandoning my own prompts once they start squicking me out, because I know a lot of people want reassurance/feedback from OPs, and I don't want to lie and contribute to stuff I dislike any more than I want to be insulting/discouraging.

does this happen to other people? how do you feel like is the best way to deal with it?
