Disallowed Comment Keys
When a comment contains any of these words in its content, author name, URL, email, IP address, or browser’s user agent string, it will be put in the Bin. One word or IP address per line. It will match inside words, SO “press” will match “WordPress”.
This should do the trick. A bit less spam to manage for you
