Bart.com is currently up for auction at Flippa, with one bid at $10,000 and a buy-it-now price higher in the 5-figures.
This auction comes a few weeks after Bart.net was lost in a UDRP to the Bay Area Rapid Transit District, which controls Bart.org and Bart.gov. You can read some details on the decision, and a lengthy discussion at this TheDomains.com post.
The seller of Bart.com is an internet savvy guy, and I’d be surprised if he did anything improper with the domain which should put Bart.com at risk. In fact, he immediately put up a generic lander for the domain (screenshot below) after he acquired it on Flippa last year for the bargain price of $5,000, and I believe this is the only site that has been live.
However, if I owned a .com domain where the corresponding .net was recently lost in a questionable UDRP decision, to a complainant that now has a track record of filing UDRPs, you can bet that I would consider whether or not I want to own that domain long term.
I’m probably not the only person that feels the same way, so there is likely (and unfortunately) a value impact on the Bart.com domain.
Best of luck to the seller for a successful auction; it will be interesting to see how it plays out.
