First I put up a video with Ron Jeremy and Angelica Sin which got age restricted after about a month.

I thought it might have been a little too wild for youtube.
But then I put up a second video with Angelica Sin and myself which was much tamer and it was age restricted the first day it went up. I think youtube simply has a hard-on for Angelica Sin.
