2) I read the official thread and it mentioned that there are merit sources. What if the merit source itself starts selling merits or creating multiple accounts and sending them merits.
Theymos would have made a bad selection when picking the sources, and would have to remove them upon discovering that.
It isn't allowed for sources to sell their merit, a punishment could go from being booted as source all the way up to getting your account banned, depending on how far you stepped out of line.
Why do we always need 10 threads instead of one? Why do we always have to address the same concerns in 3 different threads?
