Hello, I'm searching for a good anti-spam plugin. The plugin must not be annoying but it must be effective. Need: The user can't say the same thing twice (so they can't spam the same message again and again) Thanks.
If you're looking for a solution which provides protection from spam of IP addresses and URL's you could take a look at my plugin, AntiPub on DevBukkit. The feature to prevent a user from repeating their last message has not been implemented; however, it will be considered in the near future versions to be added.
