We have considered this, all of these things will be examined during the evaluation process of the application with ICANN before any approval to operate the TLD is granted. We could also police our domain and revoke users who use it for abuse but that may be too costly. But you are right that fundamentally we must protect the reputation of the TLD at all costs and that will require imposing certain limits on its use.

You should read their proposal. Specifically, the first "core feature": one person, one domain. If you want to squat on a domain, go for it -- it's yours, and that's the only domain you're getting.

I suppose this will be done by ID verification, which is a complete and total non-starter for me, but they do have a vision of some kind.
