There are two kinds of spammers that you need worry about: spambots and human spammers.

Spambots are unintelligent software programs that automate the posting of spam and can usually be easily defeated since they are rigid in their behaviour.
Human spammers, on the other hand, present a greater challenge since they can bypass the traps that catch bots and can quickly change their behaviour.
For example, you might have run across a spam post that says something like this:
“Interesting post. It’s almost as interesting as making $700 per week working from home…”
Why would humans be spamming your forum and how can this make money? Most forum spammers aren’t trying to get you to buy something, they are attempting to get higher rankings in search engines by creating lots of links from your pages to their own site. In other words, they’re trying to use your community to boost their SEO.
Nevertheless, you don’t want your community forum to be riddled with spam—that being said, here are 9 suggestions on how to defeat the spammers.
This tells search engine crawlers not to follow the links and therefore, SEO spammers will derive no benefit from spamming your forum. (Vanilla’s links are nofollow by default.)
Captcha’s are those slightly deformed images of words and you see on sign up pages. Captcha’s do a pretty good job of keeping out spam bots.
Ensure that you require your members to confirm their email before you allow them to post. Bots and humans can get around this but it’s an extra bit of efforts that most real people won’t mind.
These plugins can automatically detect suspected spam based on links, IP addresses, email addresses and the comment itself. Keep in mind that these plugins are not 100% effective and do sometimes return false positives.
A frequent trick used by spammers is to create a comment that doesn’t look out of place (For example: “This is a great post, very insightful.”) and then will come back after a couple of weeks and edit the comment to include spam links.
Ask members to help out moderators and flag spam. In Vanilla, this can be done with the Spam Reaction.
Moderators and admin should review the spam queue on a daily basis, ban spammers and delete all their content.
Only allow members that have proven themselves and have a reputation to be allowed to post links. In Vanilla, it’s possible to prevent members with a low Rank from posting links, editing comments, etc. Ranks are earned by accumulating reputation points or making a certain number of posts.
Provide information on advertising and partnering opportunities you might offer and make it clear in your community guidelines what is and what is not acceptable promotion. This can help with accidental spammers who are trying to legitimately sell something to your audience.
While spammers are always looking for ways around your defences, following these suggestions will help to eliminate spam.
