Heh, nearly all of us who commented in that had our posts deleted
That is one very weird thread/posts. If you look at the writing style and use of the English language, it could be argued that it may be a totally different person behind the account now. Personally, I am not sure, nor do I really care, but there is a clear difference if you look at the posts and changes over time.
As for the matter at hand, this user has backed out of 2 auctions recently after they had ended.
One being Crypto Imperators 1/2oz Gold 1 BTC Coin #1, which they won @ 1.5 BTC (plus funding amount of 1 BTC). They did not honour this bid and backed out, because they "didn't want the coin".
Then there is another thread in the Collectibles Section, where they won an auction for 2 Genesis Coins (which are all unfunded by nature).
The proceeds of this auction were going to the Salvation Army, so, a charity. They did not honour that bid either, for reasons that aren't quite clear - as they seem to contradict themselves. Check for yourself. Had they read the thread before making a bid, what they were bidding on was clear as day.
There is another case where they bid 15 BTC on a BTCC Mint Bitcoin Block. They did not win this auction however, so we do not know what would have happened had they done so.
It is pretty clear that this user does not read the entirety of a thread before making bids, which they then have no intentions of honouring because it is not what they were expecting. I have personally asked them to stop doing this, and to read the OP of a thread before making a bid, as this habit is not going unnoticed. It is downright annoying, and when it comes to a charity auction, plain down wrong.
