Hi Paul or Brad,
I wanted to suggest spam prevention measures.
I think people should have enter a valid phone number and receive a code, where they must text it back. This way, spammers will be stopped dead in their tracks before they register.
Also, I think you should have a picture collage in the registration process, where “people” will have to select a specific object within the picture.
Another measure to prevent spammers, is to ask people specific questions. Such as, when was Windows Vista released? Who is Bill Gates? What software was Clippy featured in. What OS was released in 2001? Etc Etc
