Ruby on Rails: Spam Gem

Question

I'm looking for a gem for my app that will prevent spamming the comments section.

So, Rails validations work fine, but when a user would spam and type the same letter say 1000 times-it would go through and obviously mess up the entire app and css structure.

Any suggestions?
