I have been using phpbb 3.X since it's release..I am currently using 3.04 and waiting for 3.06 to be released before I update my board.
However, I just checked my inactive users and found 31 PAGES of them. I cleared out a gazillion of these inactive users about a month or so ago and now I have 31 more pages of them...I have CAPCHA enabled and also a "special" field (Input your City and State) to reduce these inactive/new users.
Is there anything else I can do to stop these from trying to register to my site???
