Block customers with a link or strange terms in their name

Do you also have the problem that bots are constantly registering as customers in your store and thus “advertising” in your admin for some strange URLS? With this plugin, you can block such registrations directly. The bot gets a meaningless error message when it tries to click on “register”.  Because we don't want to give him a tip as to what the problem was.

Version 1.1: 

You can now also add terms yourself if, for example, lots of “customers” register with the name “Bitcoin”. Simply leave a space between each term. And you can decide whether to differentiate between upper and lower case.
Already “too late” and you already have hundreds of bots in your store?  You can delete them all with a click of the mouse.
