So, I sort of screwed up on multiple accounts

[lil_azn905]

I accidentally made an account on this site that had the same name the account I was going to sell.
Is there a way to deactivate the other account I made 1-2 days before this account?
Am pretty sure on all gaming forums, having multiple accounts with the same ip will result into a ban/suspension.

What's your other account username? I don't see any IP matches
