It imho has run dry quite a bit lately. Most of the old sources of Amateur Stuff are now dead (to begin with things like webshots, myspace or the beginning of facebook) and Instagram is censored to a high dregree. Most of my favorites are at least five years old
Some great newer stuff like semiamateurish porn from nerdyfaery is there, but it is rare. Even Most of abbywinters great pee things are many years old.
