Indeed. The resource I gather suffer from this but imagine you have 10 villagers on stone/gold and do this method.
10 gold every ~2 seconds = 300 gold/min. There is a cooldown for the supervisor to collect all of that but technically an almost infinite gold gain.
So, in terms of tournaments, maybe a word from the Devs @SavageEmpire566 ? Is it intentional / fine or an exploit?
