@lyman - It doesn't seem like you want an honest appraisal. It sounds like you're more interested in confirmation of your own bias toward this name.
The name has a lot of issues that hurt its value:
- It was registered only two months ago
- It's not registered in any other extension
- No existing businesses or websites contain this term
- Its meaning is negative (as others have mentioned)
Could it be used to post negative travel reviews? Sure, but no one is going to pay much money for that kind of domain name, especially when sites like TripAdvisor are already well established.
Comparing to DoNotPay.com doesn't make sense. Not paying for something is a good thing. People love not paying.
Comparing to DoNotSell.com doesn't make sense either. Their main site is a .org, since this is a non-profit initiative. Do you know how much they paid to acquire the .com name? If you could find out, then that might be a good place to start to assess the value of your name, but it would only be a start. Many other factors would need to be considered, and I suspect they didn't pay that much for it anyway.
I would list the name at $999 for the year, and I wouldn't personally renew it. You might make a lucky sale, but remember that this name sat deleted for six years before you bought it. For six years, anyone could have had it for $10, and no one registered it.
As
@MasterOfMyDomains said, you ultimately need to do what you believe is best, but all data and common sense is against you on this one.
If you develop the name, whatever value you get will be based purely on the quality and money-making potential of the site. It will have nothing to do with the quality of the domain itself. These are two very different questions, and this appraisal section focuses only on domain name quality alone.
Good luck with it!
