Mass deleting Spam-Bot's

[Gardarika]

I've got 16.000 Spam-Bot's on my forum, how I can delete them all?

My experience with pruning members you can do 100 at a time. I just delete all members with 0 posts.

Depending on what your max_input_vars (a PHP variable) is set to (commonly 1000 on shared hosting), then that is how many users you are able to delete at a time. So, when you set your criteria in admincp > Users > Prune/Move Users, make sure it only lists less that 1000 users when you click Delete.
