Hi I recently found ZB Block and setup on my site. Its an amazing tool. I was seeing lots of Bots/Scrapers etc coming in and using up my "Maxmind" GEO lookups. I have scripts to check against UserAgent lists but ZB Block is now doing the trick of blocking them. However.. I think with standard Signatures - You need to monitor to make sure real users dont get blocked. I can see a few with Genuine "old" browsers getting blocked out.. And some connecting to some Dynamic pages ( with lots of Variables ) i have getting blocked I also have Wordfence installed so not sure if I am overkilling.. But ZB Block is worth a look for anyone wanting to keep the Spammers/Hackers/Scrapers at bay. Cheers!
