RE: action-334, issue-112, a summary on sub-domains for exceptions

Is the concern that a bad actor would take advantage of the wildcard feature to piggy back off of a trusted domain versus just ignoring the DNT signal all together?

Thanks,
JC

Even if the proposal is to allow only the TLD to be wildcarded, there is still a similar issue:

yahoo.kp (.kp registrations are operated by the North Korean government) yahoo.aero (depends on integrity of the .aero registration process)

And then there are the nearly 1500 new TLDs that ICANN is currently considering, including:

yahoo.cam
yahoo.casino
yahoo.corp
yahoo.foo
yahoo.game
yahoo.international
yahoo.삼성

> If we allow *s in the suffix someone could make the call  for yahoo.badguy.com with yahoo.* .You could only allow it in TLDs (.fr, .com, co.uk, .co etc.) but some of them have more than one component so you would need a lookup table to isolate them. Even if you just matched  for subdomains you would have to have another parameter in the UGE API function to specify the range of origins, and the domain matching implementation by user-agents might be more complex. I think it would be a lot easier to use the same-party list which can be as long as you need.
