Honestly, it's not just the community, but it's also what is currently being published and translated. A lot of popular manga, rightly or wrongly, is targeted towards men, and the lewd stuff is popular. The twitter manga that teases and promises more on fanbox, that stuff sells. It's relatively low-effort and easy to generate revenue. People are interested in that stuff.

I'm personally alright seeing that stuff, but I'd like to see it more clearly labeled so it can be skipped or filtered. [DISC] with oneshot in it isn't enough, probably something like short or tweet or something along those lines.
