Yes, I would if it’s true. Because they aren’t implemented on that many mmos in a way that they actually work. I remember reading somewhere in the forums that CSGO also still has hacks while spending the record amount of money developing their anti cheating software.
Afaik, for mmorpgs it’s usually much more simple to develop bots and cheats than for fps mmos. And for 2,5D it might be even easier?
Usually captchas don’t work because they aren’t updated often enough. If the botters needed someone supervising them, it would make gold farming less cost efficient. Considering how easy it is to implement it in a way it doesn’t bother players, I think it would be worth it. Not as a definite fool proof method but as an extra feature to harass the gold sellers.
