You can not guarantee for someone else that key wasn't used, as the user that gave it away can't guarantee it. The scenario of the key being ninja'd is much more likely than the key being a duplicate or the op giving a key they already used for instance but that doesn't mean the others are not possibilities and as such the wording he used is perfect, while yours is inferior in this scenario. Op might have activated it himself, might have given it somewhere else, someone might have stolen the key from him, the website might have given the same key twice, and someone could have used the key but didn't care to say thanks.

Now if you have any perception of time, multiple scenarios could have happened to that key in between the time the op posted it, and it between the user that tried to use it commented that it was 'already used'. By saying 'already used', it obviously always, and it will always mean that at the time the user that said 'already used' that key was already not working at that time. You yourself accused specifically warriot and told him what he meant to write in your opinion with a phrase that means exactly what he wanted to say which is different from what you think it means.

Like double read what you type sometimes. I just gave you a reason to understand why his wording was better than yours in the end mostly because you always go after people for the stupidest reasons in the discussions. It could've been gog that provided a duplicated key, or someone brute forced it or some other reason. That wording doesn't specifically accuse the gifter/poster, saying 'already used' means the key could have been used the original owner, could be a duplicate from gog, could've been stolen, and of course, ninja'd. Has nothing to do specifically with lugum, and I didn't specify 1 single thing but 3 different ways why a key didn't work.
