How do I Mass Delete over 45k Inactive Users?

[jazmos]

We have over 45,000 Inactive Users Awaiting Email Confirmations in VB 4.2.2. We want to delete these users that have been inactive for 90 days with 0 posts.

The prune user group option lets you do 999 users at once but I have to sit there and click 999 users one by one to delete all at once. Or if we do a promotion, we are still limited to the 999 at a time.

I tried installing the "Users Clean UP" product Vitaly created on here but that seems to not be running on VB 4.2.2.

Much thanks in advance for your help!
