I always worry about spam and spammers when I first start a forum. Its probably because I have seen so many other webmasters fall victim to spamming. I myself do not support spamming or enjoy it at all. So, through my years of experience I have found several ways to either slow done spammers or almost stop them completely.
Since most spammers are just automated bots built for your forum software, then adding a Captcha or Recaptcha field basically confuses the bot. This is one way to prevent most spam bots from victimizing your forum.
Adding an extra field that is required is another way to prevent spam. As, most bots are set to fill in only email, username, and other basic required fields. Adding your own personal field like “Favorite Band” will prevent the bot from signing up.
This function comes with almost every forum software currently out there. It allows you to set a certain time to where a member can has to wait a specific time in between posts. It will allow you to control spam easier if you are under attack. I wouldn’t recommend setting it too high, as it could make some of your members a little cranky.
Like WordPress, some forum software have started to implement Askimet into their coding. This will definitely help as it will prevent some of the top spammers from posting on your forum. The only problem that I have found, is that “true” members are sometimes prevented from posting. This has only occurred when the members were posting either to fast or having links in their posts.
– My favorite and highly recommended!
Stop stopforumspam.com lists all the latest reported forum spammers by IP and Alias. Its list is huge! There is also modifications provided that will prevent spammers from signing up under a Russian email and will scan the list of stopforumspam.com to see if they have been reported. If they have, then they will not be able to sign up.
So, those are the methods I have used to prevent forum spam. I have also used Email Verification in the Past, but some members did not receive the emails. So, what are your methods of stopping forum spam?
