It seems to me like the existence of @acc negatively impacts user experience, especially by punishing errors, while not providing any significant value.

Additionally it seems to have access to at least calibration, which is not part of API, and this has an unfair advantage over other bots (and in practice humans).

The only upside to its' existence I see is extracting Mana from circulation, but the amount does not seem very significant in the total scale.

I can be reached on discord if you want to discuss an argument in advance to limit your risk / maximize profits.
