It’s been brought up before, the trick with them is timing and having them be hard enough a bot can’t simply do it, but easy enough to not inconvenience people.
I wouldn’t mind one every 5 games made or something but plenty of people have pushed back on any, which I can also understand.
You mean an AI on the server side detecting bot vs player playstyle? Not a bad idea. The good bots however will train their own AI to mimic human playstyle as a countermeasure 
It’s a never ending cat and mouse game.
If there was a game that could be played by simply breathing, I’m sure someone would want to cheat in that game…
I’ve come to think of it as “Game Genie” syndrome.
Yeah it really is 
sure bots cant be prevented per se
but blizz sure can basically nullify the reasons to bot, with the biggest one being the heavy rmt possible
while we are discussing blizz and bots problems with d2r, blizz is taking legal actions against 3rd party orb sellers for Immoral
That’s hillarious, and sad.
Yeah… because bots can’t open chests…
Sorry but… you stupid.
If bots could be prevented they wouldn’t be in every single RPG that has a grind… you cannot stop bots or automation its literally impossible.
Please no Captcha… that is a horrible idea and suggesting this is pathetic.
Not to mentions Captchas will not work.
Runescape tried captchas before and bots just started to use programs which you would load up and then enter captchas for people earning credits you could use while you botted…
Just accept bots will be here stop giving weird useless ideas lol.
There’s a reason it has been in use for decades my dude.
Maybe you’re too busy yelling into the wind and calling people pathetic on the internet, but reCAPTCHA is ever improving. Google’s implementation alone is over a decade old and uses top of the line machine learning algorithms to detect bots.
Is it perfect of course not, but it would in fact stop many bot attempts. Is it an arms race, yes obviously, but old ideas are not all pathetic or idiotic. They get used for a reason.
You can’t be serious. Adding recaptcha into the game is such a horrible idea.
Punishing the players.
Adding CAPTCHA, RECAPTCHA or whatever only hurts the human players.
I’m not going to play a game if it’s going to ask me every 5-20 minutes to click a checkbox, then when it doesn’t believe my tick of the checkbox is genuinely human, it starts asking me “Pick the squares with the cars” or to “right” the images.
My point is captcha is designed to stop bots. Do I think it sucks in a video game sure. But it has existed for decades stopping bots. That’s what it is for, and it has a proven track record of doing that job. If people want to stop bots it’s the easiest thing to do.
As stated above, using some form of incentive would help soften the blow. But I’m also happy to not waste any more time on this if we want to write off a thing that works as pathetic and horrible. Fine by me.
They can just make an “AI” that monitors players, given enough data it will recognize bots just by where they click on the map and repetitiveness that a human being can’t sustain
Then botters will add randomization trying to mimic humans, but again with enough data, the AI should be able to keep up.
It can be an on going battle, similar to how google’s captcha keep on evolving. It will literally check your cursor movement before you press the box to determine if you are a human or not.
So, if there is will, there is a way. Unfortunately, blizzard has no interest into implementing something like this as it will require too much work.
Yes, hello Mr. Musk… I understand that you’re now selling a Tesla bot… It can do house chores? Great. OK, the big question is: “Can it play Diablo 2”?
Elon is actually Njaguar.
How will you prevent the bot from opening the chest?
Do you have to solve a CAPTCHA for it?
No thanks, I don´t care if botters gonna bot, if the measurement against it affects my gameplay in a negative way.
Hmm… hopefully an interesting mechanic after you did terror zone 
they should just ban botters and problem solved.
HWID/IP flag and put warden that would check every few hours for suspicious activity. then ban them every week. they will be gone in few months.
Only thing that you can do to fight bots is banning them over and over.
Since they will try again and again this solution also gives Blizzard money from selling new copies of D2R. This is an endless war between legit players/DEVs and cheaters. Unfortunately most of the time cheaters win.
They dont ban that often to keep bot technogoly from evolving too quickly. If they banned bots every week then bot makers would learn faster how to go undetected.
Skynet will go live and before you know it Elon Musk will reveal himself as a Hybrid robot alien and force humanity into forced bitcoin mining labor camps.
Good! Then add masses of major improvements to D2R
Purists can’t say it’s not D2 anymore because where there is a will there is a way
If you want to keep it D2 and change it you can
