I would tell her straight up and the key most important thing that people tend to forget....
THE INTERNET IS NOT PRIVATE!!!!
If she is cool with her family seeing her pics and her day job has no issues with it and she has FUN with it, go for it. But I see soo soooooooo many times where these girls somehow think the internet is private and don't give that even a thought, much less a second thought. Make VERY sure she knows this..... that her family, friends, co-workers and everyone else is likely to stumble on the pics, a fake name doesn't change what she looks like..... been down that road more than a few times.
Ask her if her mom and dad and grandma and grandpa see the site, what would they do or say? Is she willing to risk those relationships?
That's the very first thing I ask anyone wanting to get into porn as content.
