SpamPatrol

Stop wasting time sifting through garbage and start focusing on submissions that need attention.

The SpamPatrol plugin will automatically detect other supported form plugins that you are using and integrate with them to process spam submissions based on your desired settings.

It doesn’t matter whether it’s a bot or human abusing your contact form, SpamPatrol will analyze the submissions and determine whether it’s spam.

Avoid playing whack-a-mole with unruly spammers that use a wide range of IPs and domains. SpamPatrol works based on understanding the message submitted to catch all the things that your typical website visitor or app user won’t do.
