My problems I see with this are:
How does it stop feed scrapers?
How does it accept credit cards without https?
And for those people reposting your stories...
You must be admin to post script tags in a wordpress post. not editors, and not on wordpress.com.
That's my 2 cents. But you get an A for effort.
Hmmm..... I would give it 2.5 stars but since the author has been gaming the plugins directory by updating his plugin's readme in order to stay on top, I would say that's slightly un-ethical and so anything that shakes my trust is going to weigh very heavily on my decision to use such a risky product.
If it wasn't tied into a 3rd party service, my review would be completely different. At this point, I won't even install it.
