Yep, JTC Anti-Spam / Anti-Hacker far exceeded our expectations regarding automated spambot registrations and spambot posting. We just posted the results of several months of using JTC Anti-Spam / Anti-Hacker on this Forum site (link below). 0 automated spambot registrations and spambot posts is pretty remarkable. During testing of things like IP blocking methods we were spending 1-2 hours per day cleaning up spambot registrations and spambot posts on this Forum site. That was costly in terms of time spent, but it was necessary research to figure out what really works and what is a waste of time.
JTC Anti-Spam / Anti-Hacker also stops automated hackerbot registrations/form submissions/form posting, but if you are using a common or known WordPress default user account name, such as the “admin” default user account name then you should create a new unique/secure Administrator user account name and delete that default WP “admin” user account.
I also recommend creating another Administrator account for your websites that is ONLY used for logging into your websites and is NEVER used for Posting WordPress Posts or anything else on the website so that that Administrator user account is NEVER displayed publicly anywhere on your website – author URL’s, etc. This leaves you with an alternative Administrator login account that will NEVER be locked out since it is not publicly displayed anywhere on your site.
