It's like, imagine I have a Stucky meme and I allow OT3 with Peggy as long as there's still Stucky and it's not a love triangle or something. And then some new people arrive and see it's okay to post prompts including Peggy, and they prefer the three of them together instead of just Stucky, so they post a lot of prompts, and then I shut them down because "It's too much Peggy". For me, something is either allowed or not, or allowed within certain parameters, but if the parameters are unclear misunderstandings are bound to happen.
