Hey, I've been added by an account on a steam group you are labeled as an administrator on. I'm pretty sure this account may be a bot account. I say this since I've seen similar looking accounts that usually send a message after you've added them asking for help in transfering items that they've won from a raffle. Anyway, Here's the account I'm talking about.
