Spambot from .hu tld getting through

A spambot is spamming my site. I’ve been using this plugin for a while but it can’t stop this spammer. It has tld .hu and I assumed they were from Hungary. It may or many not be the case because you can buy any tld and use it in any country and on any server.

It keeps getting through and I’m going to try and pinpoint where it’s coming from. What’s unusual is that I have every country except the US, UK, Canada, and Australia blocked.

What do I need to do? Everything’s updated (the plugin and database file).
