Re: What do your spam signups look like?
Hmmm – I installed the Plugin from Dennis Morhard “Invitation Code Checker” (https://wordpress.org/extend/plugins/invitation-code-checker) and changed the text a bit, so that my users know, which the code is when they register. Since then (a couple days now) ZERO spam signups… I hope it stays like that and the plugin is not too upset, that I misuse it
