Wouldn't that be somewhat of a positive? One of the common complaints you see about troons is that they put absolutely zero effort into passing; if lurking in a beauty thread or asking a good question helps towards their passing efforts, that seems worthwhile. Being judged is an unavoidable part of the feminine experience, unfortunately, so why not try and make it a little easier for all comers? Provided the thread isn't overrun and natal women can still converse freely it seems harmless enough.
The posts all seem "normal" to me, anyway. I dunno.
Of course, there are no women on the internet, so really it's a moot point.
