Well .. we’ve tried few solutions including 3rd party shit but none did the hell of the job that this plugin did. We’ve didn’t activate or use all features and just stick with exactly what we needed. The fact that allow(ed) to manage blacklisted IPs and see where are weird visitors came from including other details was pretty enough at that time for us. No conflicts with other plugins/tools and no failures excepting the fact that if you get banned on your own site you gotta get the unban link into administrative email or, easier, to delete the entry from mysql 😉
Overall, if you start using it you’d have no absolutely fucking reason to uninstall it!
Hope that in future won’t have to search for something else.
