I was the seller of gay.uk and wanted to wait until the sale had been resolved one way or another before commenting here.
After the auction finished, I emailed the winner (Tom Goolnik) to arrange the transaction. The day after the auction he replied and claimed that his maximum bid had been £10250 and some kind of error had occured. I found that hard to believe - computers don't alter user input - but I contacted Denys who runs Domainlore and told him what had happened. Denys looked into Domainlore's logs and revealed the following:
Tom had spent last 20 minutes of the auction refreshing the auction page every few seconds and watching how the bidding was evolving (with his auto-bids increasing from 10k towards 20k) instead of urgently contacting Domainlore customer support to revoke his incorrectly entered bid (if he didn't know how to do it himself right there in the bidding form, which was also displaying his maximum proxy bid amount of over £21000 all that time).
When the auction finished Tom shared a link to the auction with someone over WhatsApp.
As mentioned before, it wasn't until the day after the auction when he emailed me to say some kind of mistake had occured.
Since then, I have been in discussions with various people about the domain and I am pleased to report it has now been sold to one of the underbidders in the auction. As this is a private sale, I won't reveal the price but I am happy with it. Needless to say, Tom Goolnik has been banned from Domainlore.
