It looks like that's a separate account that's linked with the other one. My posts and profile still exist. Sending a private message to Frogging101 oddly causes Brooks572 to indicate "1 new message", when the inbox is empty.
Trying to get a password reset email for Frogging101 with Forgot Password returns a message saying that there is no such account. Strangely, the same thing happens with Brooks572.
Before you jump on me for having more than 1 account, I didn't create this account. This account pretty much appeared out of nowhere.
Also, I can't redeem my code on either account while Frogging101 was still working. I still can't redeem it with Brooks572. It's probably something to do with the fact that neither of my accounts fully exist or are corrupted.
