It's on folks. Today I finally had some freetime and motivation to take care of the problem.

1. I added a new text box to the registration that requires the correct answer to continue. Since the question and answer is custom, this should stop the automated spammers from signing up all together. My fingers are crossed that this works, because the image verification doesn't work good enough anymore. 90% of the spammers all signed on within the last 5 months.

2. Members who don't confirm their email go into an un-confirmed usergroup. I did a mass deletion of any member who was in that list for longer than a week, plus the ones that were real obvious spammers.

3. Any member not having logged on in the last 18 months with 0 posts, gone.

4. Ran through all the leftover 0 post members and deleted anyone that looked suspicious. They are pretty obvious because the email is weird and 9 out of 10, their joined date and last activity date is the same, meaning they joined and never came back.

All in all, about 200 members or so were deleted permanently!
