All i know is her video where she does the most her "breastfeeding educational video" is still up. so as long as it is i will take it as a good sign youtube isnt on her too hard....yet
Content like this that isn't a disguised advertisement or based entirely around nudity is exceedingly rare these days and often gets deleted with the sharer almost never making backups. There's no statuete of limitations for video takedowns so even stuff that's 5+ years old will get taken down if it's triggered.
If I wanted to see random boobs, there's thousands of other places for that, but those don't have the amateur angle that makes videos like this special.
