Look here if you have bought revoked gifts:

1. Accounts listed above includes the owner of this account and one of his alt. trading account.
2. If you have bought revoked gifts, contacting the seller via these accounts for resolution is more effective than contacting Dispenser.tf.
3. If needed, these are the accounts to be reported to Steam support.

Hey there. I'm GR. This is my gift bot, that allows you to buy games from me automatically at any time of the day, via the required keys/ref.

In case you do not trust the bot, or would like to only trade with me personally, add me on Steam. (I'm online for a few hours per day.)

Don't forget to leave a rep after a successful trade!
