Question regarding PS1 Vets

[Kujo]

Forgive me if this has been answered here before. I tried googling and couldn't find any info.

I noticed Higby said PS1 vets don't need beta keys. What happens if they do use a beta key though? Does it unflag their accounts as a PS1 Vet and use the beta key instead?

I ask because I'm a PS1 Vet but last month I put in a beta key from Twitter that a friend gave me. After that, my account wasn't flagged for the free 30 days of PS1 and I had to contact SOE support to get it. So I'm a bit paranoid about my PS1 Veteran status with regards to the beta.
