I have been working with a serious buyer since last October and we have exchanged dozens of emails for the last 6-months. During that time he slowly come up on the offer. A few days ago he sent me a message saying it was his best and final offer for the dot-org name he was going to use for a new startup nonprofit organization. He asked if the price was okay with me and needed to know if okay right away. It took me until the next day to decide and it seemed certain we had a deal. However, he had already purchased an alternate name the night before via Godaddy or Afternic! I asked why and the reply was he believed I would not accept his price and he noticed a very similar name for sale via GD/Afternic so he grabbed it right away rather than wait to hear from me the next day. He explained how he typed in my name in GD to double-check price and on the same GD page below my name he noticed the plural version of my name for sale. Not only was the plural for sale it was also 6k less vs my singular name i.e. 2k vs 8k. He also indicated a reason he got it was by seeing it under my name on GD and not because he was looking for it. When I told him the plural was far less known and significantly less used so maybe he should have both names (example.org and examples.org) he said it was good enough for him (but admitted my name was a lot better) saying he can use the 6k lower cost as working capital for the new nonprofit. That type of scenario I am sure has happened to a lot of NP members but it's unlikely you would know about it. It really SUCKS big time when you think about it and how GD, DAN and others do not truly care if the visitor buys your name or an alternate name. To help avoid that I recommend you use your own landing pages, or as an option find a place where no other domains show except your own name(s). P.S. From messaging the best known member of NP there's a place named squadhelp (who I am not familiar with and never used) where it can be setup so someone else's similar names will not be there. Its a powerful plus, IMO. However the fact so many buyers automatically check at GD makes the situation hard to work around if not impossible to resolve.
