Lots of folks ask 'why i get spammers in my forum', 'i have lots of spam', etc.
Let me tell you,.... i dont get spammers at all on my working 5 years old forum.
Simple, i run SMF RC3 and a couple mods.....
1. First off, i use SMF's RC integrated security question. The question used is related to my forum genre. I run an automotive forum and the question is simple. "How many spark plugs a Chevy Avalanche has?" Answer is 8.
Do bots know this? No.
Dont make question like: "What color is the sky?", "What color is the grass?" or "2+2=?" Make your security question related to your forum genre that your guest know the answer to.
2. I also use SMF's integrated "profile Fields".....(also available in the mod site for 1.1.x users).
The mods i use:
Vbgamer's "Avatar Select" mod: http://custom.simplemachines.org/mods/index.php?mod=368
青山 素子 "reCaptcha" mod: http://custom.simplemachines.org/mods/index.php?mod=1044
These simple mods available in the mod site
and the security question should stop bots and spammers from registering.
Try them out and have fun
