Yeah, I played another server where if you’re solo farming, an npc image will pop up asking to enter numbers, failure also means getting booted out of the game. That’s counts a kind of captcha. But yes, it bothers people who AFK without farming anything, really.
Your post in this thread is good. I agree with that one but I’m posting a different kind of solution that utilizes the weight system mostly, rather than server-side protocol. So the latter is up to them to implement and to others to suggest.
The post about NOT DISABLING z-button attack, which would also apply to not disabling attack in general, I cannot agree with IF you mean z-button shouldn’t be disabled even after the character gets 100% weight.
Sure there are legit auto-attack builds, but it doesn’t hurt to take the time to drop some items to shed weight or watch your weight limit from time to time, rather than insisting the z-button remains usable at all times regardless of weight. Having an auto-attack build does not mean you get to go AFK in a game. That’s no different from botting, really.
Keep in mind my OP said this DOESN’T solve the botting problem. It’s meant to PUNISH botters, sadly that extends to AFK farmers because the gameplay method is the same. The purposes of botting was to originally gain exp and loot for oneself and then brag about being high level without doing jack of a work. Only later it evolved to selling accounts and currency for real money. There’s nearly no difference between botting and afk farming, both require no effort to get exp and items.
