Enom Locking Legitimate Domains

According to the Herald Tribune, Enom are locking names on a US Treasury blacklist, preventing the owner from carrying out legitimate business. The owner is in Europe, selling travel packages to many places, but including Cuba. Now what on earth is wrong with that? The Americans may have problems with Americans going to Cuba, but the Brits and the go to Cuba in their droves. It is a VERY popular destination for us every summer and packages are sold by almost every major tour operator in Britain.Now I have a reseller package with Enom. It is therefore with some alarm that I hear stories of my DNS provider closing down entire businesses with no good legal reason. I guess if I was Enom and the US treasury came and shouted at me, I would buckle too… but in this case the Treasury should be absolutely ashamed of themselves.
