Image Verification for Contact Us

[Chicago_VLNU_4s]

I'm tired of checking my e-mail and dozens of these damn spam bots sending me garbage!! Is there any system of what not for image verification when using "Contact Us" so that only legit messages get through?

nvm, I see there's a result for "Similar Threads"

With vB 3.6.4/3.5.7 this can be turned on at:

AdminCP -> vBulletin Options -> Site Name / URL / Contact Details -> Allow Unregistered Users to use 'Contact Us': Yes, but Verify Image
