Changed human verification and now I am seeing tons of spam

[austinelse]

So as the title says, I changed my human verification from a question to a recaptcha and now I see near 100 spam bots trying to register every day. I have attempted to ban email addresses but this seems like an steep uphill battle.

I'm looking at using Spambot Stopper by kh99 for a method to prevent them from registering at all. This is the first plugin I will be installing on the forum myself. Is it pretty self explanatory as to the necessary steps to make it work? Is this plug in one of the better to use against spam bot registration?

Any help is greatly appreciated.
