Okay, I'll try and respond point by point because that is one gigantic message.

1. I was trying to be polite, but your original comment lacked any meaningful (read: HELPFUL) context whatsoever. It didn't even inform me specifically that the winner had an issue with the key. It was only until your second reply that I figured that out with some degree of confidence (and only a 'degree'). You are not doing a particularly great job as a mod if you are expecting people to infer the majority of the meaning behind your messages rather than simply stating it. It's a bafflingly worded comment, even ignoring the whole "mod note" with a link that apparently I am expected to know isn't for me (even though it's in the message sent to me). Honestly? 100% yes it would have been more helpful if you'd never commented here at all. Assuming you did come here to try and offer some help for me, perhaps listen to that feedback.

2. I am operating on the assumption that when Steam itself says its a "ROW" key, it is a ROW key. This is not some sort of grand, leap-of-faith type assumption. Again, with the completely pointless (read: UNHELPFUL) and weird patronising from you. It is a totally fair assumption to make as far as I'm concerned. But yes, you are right. I now know that steam cannot be trusted with this, thank you I guess.

3. Once again, I have very patently not "prevented" anything. It is weird to me, that when gifters cannot contact the winners of their giveaways on this site, you moderators are quick to recommend reaching out to them by email or on their ((connected)) steam account. This has happened for me before. But here, in this case, when the winner cannot contact the gifter on this site, apparently it now becomes very wild to expect them to try and contact them on steam. Regardless of your opinions on this though, I have not "prevented" contact. I am curious though exactly how you would interpret a key being revoked a few weeks after giveaway (or months or years), and the winner having been blacklisted by the gifter before that. I guess no one should blacklist anyone on this site, because they'd be ""preventing contact"" in that rare eventuality...
   I love the accusatory wording by the way. I redeemed the key because you came here, gave zero meaningful context but implied the winner couldn't redeem the key - and uhhh, expected me to do what, exactly? Not test the key? Is that truly an unpredictable and strange series of events for you?? How have you been THIS unhelpful, and don't realise at all the role you've had in this chain of events?

4. You are evidently correct. I wonder if you realise though that you wouldn't have had to write those 700+ words to me if you'd just, in your original two comments, stated the fact (which I now know you were aware of) that the winner couldn't redeem the key because of a region restriction, and that the key likely came from a region restricted bundle. I am going to have to guess again that instead of actually trying to be helpful here, you were instead trying to make some condescending 'lesson' to me about not blacklisting that early and had no real interest in being helpful or actually sorting out the issue. Thanks again?

5. Nice, thanks for answering a question that is obviously no longer valid or going to be asked by me I guess? More useless (read: UNHELPFUL) patronising, that absolutely isn't "just stating info".

6. Before this message, that finally provided me key detail, you provided little of nothing. Make no mistake there, please. This has perhaps been the least helpful and most confusing interaction with a moderator I've had yet. I really question why you conducted yourself in this way. Just out of pure spite at this point - I feel the desire to keep blacklisting winners I don't like early. So if your intention was to remedy that, I can't say you succeeded. Because the issue here wasn't actually rooted in my blacklisting, it was rooted in my ignorance of, and failure to check the region restriction. If I hadn't blacklisted the winner, they still would not have been able to get a working key from me - and the giveaway would either of been deleted or remained as it will now. There's not much difference in that chain of events compared to this one, other than your confusing, unwelcome and unhelpful input. And I guess my ability to re-giveaway the key? Though I can't say this is a mistake that I'll repeat now I realise the importance of being sure of region restrictions. It is also clear to me now that this is a worse issue than when I was previously very active in giving away games.

"In short, the winner could've simply given 'Not Received' feedback and move on with their life. Instead they wanted to reach out to you but couldn't"

Again, this is just wrong. Writing to me on steam takes less time than it does writing a message, with supplied 'evidence', to support. You know this. And literally expect this, if the case were reversed....

"I went out of my way to attempt two things: Help you with your giveaway, so you can potentially resolve the issue and help the winner so you guys can talk and figure things out."

Please re-read your initial messages and get back to me on how you actually think they help with this supposed aim. You did not tell me the situation. You did not tell me what was actually wrong. You did not give me recommended steps. You didn't even specifically state what key it was. If this is REALLY you "going out of your way", I have to ask - what on earth are you like normally?
Again, if you came here to be helpful, let me repeat: you have not been helpful to me in the slightest, other than finally telling me now that the key was not ROW and steam's "ROW" isn't trustworthy.

"That you want to take this as 'condescending tone' towards you - I'm giving you plain information, nothing more nothing less."

IF ONLY that were the case, man. I'd actually take you being condescending but actually still giving me information, over you giving no information at all. You did the latter while also still being condescending, which is sort of crazy.
