I am facing lots of problems with spammers. In my forum, I have lots of spams posted each day despite my earnest efforts to prevent them. So, I am just curious whether I have a loophole in my protection, or it is normal in forums (where mods have to delete the spams on regular basis). As I have just started my community with no real number of members, I don't have any person to help me moderating, so all I have to do by myself.
The measures I have taken:
1) Mandatory user email confirmation during registration
2) Set my registration timer to 25 sec
3) Using Q/A captcha with multiple question
4) Changing captcha Q bi-weekly (Q are like what is the 5th character of ...., or some simple math ... are they too simple?)
