spam has, and will always be a problem...some sites appear to have little or no spam, but it is really the nature of those forums that drive the spammers........On one site I moderate I see one spammer a month and on another it is daily....now on the one that sees little...it is a jeep forum for people who like to mud and rock climb....the site has over 1000 posts a day and we are very active watching the site, the site that sees alot of spam is a heating and air conditioning site that has about 50 posts a day, so spam posts sit on the site longer because there is less moderator attention to it. I know it is not the answer to why, just something I noticed on the two sites. I also noticed that sites that allow for alot of advertising usually see alot of spammers
