I wonder what is so hard to tell us is this legit and OK or not. What does it means "we are looking into it"? It means that they are not sure if this thing is legal or not sure if people are actually doing it?

A simple "No" it is not allowed and forbidden or "Yes" you are welcome to do that is more than enough for an answer. If these exploiters will be left without a punishment expect very soon half or even more of the player base to start "playing" like that, isn't this obvious for the Devs? Personally I will do the same next season if I see no measures being made against these players.
