At least right now – I suspect the intersection of "TOR users" and "people happy to provide email address confirmation" is so small as to be insignificant. Any development effort aimed at that cohort could almost certainly be better used elsewhere.

Having said that, I'm currently trying to make a point of using TOR for regular and mundane uses - particularly if using government sites - just to increase the amount of "legitimate" tor traffic. I'm also (carefully) intentionally de-anonymising myself while using tor like this - identifying myself to local government websites while doing "ordinary" things while connected over TOR - I booked an extra trash collection recently for example. I don't suppose my local council website managers even notice, but I like to think my local PRISM equivalent operators see traffic like this and think "WTF?" ;-)

(But like the parent-poster, I've suffered forum-trolls, and given the time and skill poor nature of most forum owners, the obvious "just ban free email accounts/tor/cellular-ip signups" is often the right, if overly broad hammer.)
