Farzaneh,
An entity registering a portfolio of at least 73 Domain Names, would in my view know what it is doing. And so part of the blame would fall under Caveat Emptor.
On the other hand the Registrar's behavior would strike as havy handed. And fraudulent, if not at least a proportion of funds would be returned. The problem of course is the recourse if two or more jurisdictions are involved.
So I do agree that we need to bake some form of recourse into this Policy, and that this would be clearly within scope (as otherwise would be silly, and worth dying in a ditch over).
