There's also another way to re-audit it. I haven't tried it but try it out.
This method also works (for those who want to reaudit their account anytime).
1. Change your twitter username temporarily;
2. Do the audit with the new username;
3. Change it back to your original name;
4. Done! Free re-audit!
You can try it for free so if you don't want to pay for those audits, you can check and see if its really working.
