I'm considering starting a forum with vbulletin. Anyway have experience with how bad the spam issues are? I have another website that allows users to post things and there is no CAPTCHA and no login required and I have never had a spam post on that part of the site. The phpBB forum on the other hand would get COVERED in spam... and you had to login there. My point is that I'll take "proprietary" over "technologically advanced and prevalent" any day. How difficult would it be to get someone to write me some sort of custom code for signing up? Changing the format a bit and the field names, etc?
there is a good NoSpam plugin..that works very nicely.. like it asks what is 1+1 obvisult bots cant answer those..and this is in addition to the captcha.... this is free..if you buy vbulleting..these hacks are from vbulletin.org
