@martin it is dangerous of cource. That is why backups exist and that is why i quoted not to hold me responsible for that plugin.
On the other hand how can someone delete 150+.000 users?
A plugin that only deleted users never logged in would be safe.
Yes, the "Never loggedin" status could work. But all users are migrated from phpBB, and I'm not sure the login data is migrated correctly. It needs to be double-checked.
This seems like a better solution but AGAIN BE CAREFULL.

Delete users
- Delete Users
- Delete Users by user roles
- Delete Users by date interval
- Delete users based on their registered date
- Delete users who have not logged in in the last X days
- Delete Users by user meta fields
Or this:
https://wordpress.org/plugins/user-spam-remover/
Automatically deletes user registration spam and other orphaned, never-used accounts. Fully logs all actions and backs up all user accounts that it deletes so that you can seamlessly restore them if you ever need to.
