Any example? (Link)
I saw that someone recently uploaded some Jr Idol content (I hope "Jr Idol" is the correct term as I'm only here for JAV and don't care for the other things here).
I don't have much info , as i'm not into that , but i guess it is legal or atleast in the grey sector ... otherwise the site would've been taken down long ago , and the uploaders captured by interpol.
Also i've heard such content is also produced LEGALY in Russia , which is wayyyyyy more strict about such things than Japan is , so i guess it's okay.
While the U15 stuff may be considered child porn in some countries with really strict laws, they aren't actually nude and allowed on this forum. There's even a seperate section to post the videos in.
I guess they won't be banning that content, you just have to ignore it. It's not my thing either so I just focus on the things I do like.
