Prune users by email adres/postcount query or prune them by ip addres
 

I've got a lot of users which are more or less abusing my system due to multiple registrations.
Now I would like to prune these users based on their email addres domain (f.e. @yahoo.com) in combination with the fat that they have 0 posts (or less then 0 posts).

However I'm no Mysql wizard and the users pruning option has way to less options, you can only prune users based on "postcount", login "Before" or "has not logged in since".
So that's more for the normal maintenance.

On the other hand I've got the ip addresses of those users, so a combination of delete the users from usergruop registered who have less then 1 post (or have 0 posts) and have registration ip xx.xx.xx.xx would do nice too.
