" analyze the crap out of sign up page activity" Do you have any suggestions for further reading about approaches to this? I do plan to do manual verification initially, but if the project is succesful, I won't be able to keep up- a good problem to have, and I don't want to optimize prematurely- but I also don't want the site to become overcome with spam before I have any clue how to handle it :)
