The basic problem is that chaumian credentials are transferable.
People who have no use for them will be able to sell them for a few
£s, and domain name speculators will be happy to buy them. Someone
who is willing to speculate $70 each on hundreds of domains can easily
afford to buy a few transferable credentials.
About a month ago I got an emailed "offer" to bid on security related
domains (starting bid $5,000!). Take a look below (I have elided all
the .net variants; he had both .net and .com). The whole lot would've
cost him ~$8,000 to register. Ones with *s were supposedly sold.
Checking with whois it seems that some of them aren't even registered,
and a few are registered to a Scott Martin.
