Based on the video I'm watching as I write this, I would call the site Sexy Round Ass Amateurs rather than Bad Ass Amateurs (although there is that whole bad-means-good thing that applies). I would also call the site One Section of XXX Raider Pass, but that doesn't have the same ring to it. It is an accurate description though. There is no real individual "bad ass" site, but rather when you select it from the drop-down menu you are just presented with network content that has been tagged "amateur."
And in that section you are looking at around 2,000 photo sets and 250 videos. I say "about" because some photo sets are vid caps and some vids are split up into clips, so getting an exact count is difficult. Also, there are no page numbers, so you will have to go "next" and "next" from page to page. Some of the BadAssAmateurs content is exclusive, but even the exclusive stuff is exclusive to the XXXRaiderPass network and not any one site/section (you do get access to everything with your membership).
The photos look good and the videos come with the option to stream them in an embedded player or download them in Flash format. The videos are average at best and sometimes worse, regardless of what the bit rate might be. The videos have no dates on them, but the photo sets are dated and they look to be updating almost every day with a new one or two or three. The content is a mix of action. I saw solo webcam dancing and then checked out a hardcore sex scene and then saw some lesbo loving. In the end, the video quality just isn't good enough to recommend the site.
