When people searched for 'amateurs' in the past they were looking for non-models. Just everyday people next door types.
Now people have to search for 'REAL amateurs' because many pay and affiliate sites used models to lure the amateur-loving crowd in.
This tells me that it takes more effort and creativity to make amateur porn using real people not in the industry. Otherwise, program owners/affiliates would just do it (use real people) instead of having to fake it.
One of the best sites I've ever seen using real people is
www.darering.com . If anyone can tell me about more sites like this please spam away.
