I am looking for 2 things:
a) near-perfect way of weeding out spam users right in Registration
b) automated deletion of spam Users, if some of these are already registered on a WordPress site
Feel free to tip any good tools that you’ve seen being used, or have used yourself. Thanks!
Will be posting about this in the future. For now, found it was easiest to just delete fake users right from the WordPress admin panel (backend). But it seems the incoming registration stream is quite constant, at a few new fake users per day, so in the long run it would be great to solve this in a bit more automated manner.
