I used to be a forum moderator many years ago. We were constantly attacked by spambots.
I found that by adding an extra mandatory field to the registration process (eg what is your favorite pinball machine?) we cut the amount of spambots by a significant amount
The spambots know that registration is seven (or whatever) fields
Giving them an extra field means they do not finish registering and thus cannot post
Keep flippin’
