No. This thread is not about restricting aged up characters. All the discussion that took place in this thread, apart from the last few comments, has been about women in general in revealing clothes. I see the aged up characters issue as an entirely different tangent. And if we want to discuss that, we should probably make a new thread for more participation seeing how this thread has already gone inactive.
However, if you want my opinion on that, it's the same as DontTalk said elsewhere. For fictional characters, "only" canonical age is not a suitable metric to decide when pictures should be allowed. Fan artists can age up the characters and draw them as adults just like manga or comic artists draw them. If character A is okay then character B should also be okay if they are drawn to be the same age irrespective of who drew them. People generally go by appearance in all other websites I have been to. In fact, people have more problems when canonically adult characters are depicted as minors in drawings, and that holds true for most of the sites I have visited.
So if you want to put down a rule for that, I would suggest to make it so people avoid "minor looking" characters irrespective of their canonical age. I don't think there should be any rule against the use of adult looking women. We have been over this in the past also. I have seen many members, including staff, having cropped **** and sexualized women as their profile pics in my time here, and every time it came up it was always deemed fine if it didn't break fandom rules. Anything more than that would be too prudish and restrictive and I don't think there is any real harm done based on
these facts.
