Thanks for reporting this bug.
The bug can be reproduced when "Twitter" is set as a "Show" or "Required" field for new user registrations.
The temporary fix is:
1. Go to Control Panel > Registration > Registration Screen
2. Set "Twitter" to "Hide".
3. Submit.
The four users in your log will need to perform their new user registration again. Their last attempt probably displayed an error page to them. Nothing was saved, but the "Users Awaiting Approval" counter was bumped up. That number should be recalculated upon the next user registration.
This will be fixed for UBB.threads 7.7.4.
