Becky,
you are the lawyer, I am not.
I just mean a concept.
Can you take down a Registered Name, just because (at least) another Name registered by same Registrant has been mitigated?
If a single Registrant has 5 Names, 1 reported, investigated, proven as phishing, and mitigated accordingly, ADC done, and 3 of the others are mitigable, I still don't like that the 5th one would or could be mitigated as well.
However as Marc wrote, you act against the Registrant (for violating the Terms and Conditions).
How would that work? Can you really unilaterally decide to take Names down, or do you have to give notice of termination of the Registrant agreement (0 to n days notice)? So they transfer the Name elsewhere, and perhaps even register the mitigated Names again.
Now you take a Reseller which has a Million Names. ADC finds 50, 500 or even 5000 in need of mitigation.
Do you take the 50, 500 or 5000 names down or do you cancel the agreement with the Reseller (for violation the Terms and Conditions). What happens then to the Names left?
Or if the Reseller is just irritated enough that they transfer significant Revenue elsewhere? There are enough accredited Registrars around, after all.
The obviously even more difficult question is how to prevent them from becoming wise to the Policy and transferring the rest of a portfolio to another Registrar, when a single one is taken down, ie before the ADC can be done?
We have not thought through the consequences of our considerations, and/or the cost.
