I get "You are a spammer, hacker or an otherwise bad person." both on the front end and back end of my site.
this happened after upgrading my admin tools. i have down graded and not had this issue. I have done the 1st step pasted below.
Go inside the plugins/system/admintools/admintools directory on your site (on older versions of Admin Tools: plugins/system/admintools). You will see a file named main.php. Rename it to main-disable.php
the second step asks you to "Go to Components, Admin Tools, Web Application Firewall and click the Exceptions Log button."
i do not have a button labeled web application firewall.
