Hi @tuner85 ,
I believe it was just a misunderstanding about how the feature works.
If you enable the “Delete users” option, it will only delete the unverified users.
Now, if the option “General > Account verification > Current registered users > Verify account for current users” is enabled, the users registered before the plugin has been activated are going to be considered unverified, and then, the Delete option will remove them.
Although the text might not be so clear, the Delete option has some notes about this matter.
On top of that, regardless of how the “Verify account for current users” option is set, new accounts will be considered as unverified, and so, will be removed according to the Delete frequency.
Now, I believe there might be a misleading info. After enabling the “Delete users automatically” option, it will run the first time immediately.
Let me know if it helps.
