There is some speculation that the sale of tights.co.uk on Domainlore.uk was not legitimate. I know both parties involved and it was a 100% genuine sale, as far as I know, they don't know each other. Even if they did, there is no chance they would have colluded or anything strange happening. They are both standup people in this industry.
Without the .uk it isn't one that I would have purchased myself, but if you are in that business and know to how to sell these items direct to the public. I can see the name pulling in a fantastic return.
I do question the seller though (I don't know who it was). The domain was first registered in 2001, so I assume the current owner would have had it some time - at least a year. If that is the case, why didn't they register the .uk last year? Seems a very big oversight by someone. The .uk was picked up in the ROR in July 2019 by the tag Servitor. He must be sat there with a big smile on his face around now.
