Just curios, did theymos pay all the mods for their work or were they doing it as a voluntary job without any demand of money?
This is Bitcointalk, Mods have their Bitcoin address in their profile. Payments are public 
Payments are public based on the transactions that can be seen on Blockchain, but is it really possible to categorize where they're getting those payments from?
I don't think theymos releases that kinda data publicly, so he/she may use whatever address to send the mods' salaries to their addresses. As well, he gave estimates and not the exact numbers in USDT per each mod paid.
