Seems like you can get banned by posting in chat youtube video links so think it could be cool to get know what kinda youtube videos you wont get banned for...
The link i posted have been posted over 500times in this site and other moderators have also seen this video in this site and only 1 or 2mods takes it as a bannable video... ?
I honestly cant see any wrong with a natural birth video. Even you have to login to youtube to see it. Also it asks if you want to watch it.
Maybe just make chat so that can't post any youtube videos in there or make clearer rules?
