Apparently anxious to get rid of a BUTCHER key for Steam due to the GOG giveaway, this trader offered me a 1:1 deal on Barter, which I accepted. Since he has very little rep and only a few trades completed in barely 2 months, I asked him to go first.
Even though he claimed to have it revealed just at that time. He also claimed to have purchased the key from HB, although showed no proof.
Following the regular procedure for this kind of case, I suggested he'd open a ticket with HB to get a new key. He refused, stopped talking, and raised a dispute.
Funny thing is that he was who provided a dupe key.
Anyone knows that no trader with more than 3K successful trades and 5 years of experience would risk his rep, much less for a game anyone can get for free on GOG. Well, this guy apparently is the exception to the rule.
So just giving me a -1 for revenge and nothing more, as expected
Anyway here is the proof of were the key comes:
As you can see from the rest of the unrevealed keys from that bundle (and all the other keys I have) I never reveal a key until a deal is done, to make sure everything goes fine.
Obviously I am not going to flag myself as a trader opening a ticket to HB support for a just revealed 10 cent key and risk my account and all the unrevealed keys that are in it (common sense), specially when there is no report of anybody anywhere saying keys for this game from this bundle are not working.
If the other trader was so mad because of accepting a deal for a game that went just free a few hours later, he just had to let me know that the deal was unfair for him because of it and I would gladly cancel it, there was no need to go through all of this and try to outsmart another user just because she has less rep.
+++rep ! Sweet and super polite trader who will make sure everything is good before validating the trade ! 100% recommend
