I too notice random female pilots showing on /m/ more frequently, I tend to leave them alone because most are generally innocent and people ask stuff about the character.

To be honest, I'd rather not see female pilots on /m/, I'd go to /a/ and ask people for female pilots if I'd want, I suppose we'll have to wait till the new rules are implented and see what goes from there.

/m/ is however a "sfw" imageboard, so anything too much revealing is just a request for a deletion.

You can also take it strict and don't allow anything else than what /m/ is made for, namely mechs, no things like "Please post more images about Fllay"
