Is there a way to delete several user in a more easy way?
Just found out more than 200 registered spambots (changed to Q&A now)
The only way I see is to delete each user one by one and that's a horrible task.
There is no mass prune feature for user accounts. But my experience is that you should ban spammers instead of delete them. When you delete a spammer it prompts them to re-register. Different spam bots will behave differently, but this has been my experience.
