Ah, I feel like I have failed to adequately explain myself properly. That's my fault, sorry.

The very nature of generals means that it's impossible to stay on-topic all the time. If you want to discuss a theoretical iM@S x Soul Calibur crossover, that's fine by me, as long as you don't get carried away with it.
Same with people posting about fetishes: I don't object to people who post Bug Mammoth-tier stuff, because they don't go on about it for hours, or even days on end. It comes up, it gets briefly discussed, and they move on. On the same note, I haven't objected to the occasional "Tenka wears a diaper" posts, because again, they're only brief tangents.

But when things go completely off-topic for the entire duration of a thread? That's going too far in my eyes.
Basically, if you go off-topic, don't get carried away. Listen to that little voice in the back of your head saying "Hey, maybe you should stop now", if you are fortunate to have such a thing.
Sexualization of underaged characters is, for better or worse, an official part of iM@S, so that's going to justifiably come up more often. Nevertheless, I think it's also best not to get too carried away with it.

tl;dr: Remember that this is The iDOLM@STER General first and foremost, not The Talk About Whatever The Fuck You Like General.
