Ok I think that is enough. I can understand when someone bought Chevereto and after a few hours he notices that the script doesn't suit him and he transfer the license. That's why some transfers are accepted.
But when people starts to sell without even ask the Chevereto License, Themes, etc. I can't deny that I get angry because no one likes to see how is work is being sold cheap. And I can tell that all the people who transfer their license keep using it at least that version because you already have it on your HDD (sure, you delete it from your disk... yeah, sure).
So since a lot of people is doing this I think that you are cheating so any license transfer is forbidden.
A few lines on the License Agreement will indicate this official prohibition from 2.1 but it's effect is intermediately. No more license transfers, period.
