Zachery,

I have been using the image verification and it had worked for some time (1 year), but within the last 2-3 months, some hack figured out a way to get around that and I was getting a large number of contact us emails and registrations even with the image verification turned on. I'm not sure how they were doing it but the registration bot appears to be attempting to fill out all of the board-specific fields.

I just added questions that are specific tech knowledge to site users and it completely eliminated the issue.

I was receiving several hundred SPAM type contact us and registration attempts even while using the image verification. Maybe I was doing something else wrong, but this seems to have completely corrected the problem.
