Check post attempts for "spaminess" on stopforumspam.com Please see http://www.stopforumspam.com/usage before enabling for restrictions and conditions
We can check at registration, but this will repeat the check for subsequent posts. The more time that passes between registration and posting, the more likely it is that the spammer is caught before doing damage.
If the poster is determined to be a spammer, the account is deactivated. The determination is made by inspecting the confidence level returned by the stopforumspam API. If that confidence, for either email or IP address, exceeds the configured $minimumConfidence, the post is denied and the account is deactivated.
