Yeah that is something different like pick all the pictures with kittens in them sort of deal and yes easily manageable with some programming if they only have so many possible variations of the captchas.
Google Turing test and you will understand what I mean, they can literally create millions of different kinds of questions that require some kind of sentient and emotional thought to respond to.
Certainly they would have to be more complicated than asking you how your day is or what your favorite color is but with enough variations to the kinds of questions that can be asked it would be a pain in the arse for programmers to sit there and do the test so many times they finally have a response to every possible question that makes them not look like a bot.
Especially considering it could ask the question randomly anytime during play, random days or hours basically the bot would have to have some kind of alert system so that the programmer has to be present every single time the test is initiated randomly without planning or preparing for it knowing when it might possibly make these test and every time that programmer would have to be present to do the test themselves just to find another question and answer to give and again a long, very long time to get enough input to properly program around the test entirely.
Unless the programmer was always available or present the test would shut down the bot and log them off and then they have to do the test again just to log back on and now they have a flag on their account for CCP to take a closer look at.
Expensive? I don’t know about that I am sure there is lots of information and technical data out there already to do these things and not as hard as anything new they implement into the game and by far more useful than a lot of more complicated features they have added to the game nobody cares about that does little or nothing for those players.
We are also talking about them shutting down bots in Eve online, not just having to find and ban them but a way to stop them from operating entirely without a player present and then imagine the work trying to run dozens of bots constantly doing these tests while also trying to gather data to program around millions of possible variations of these tests.
Expensive compared to what? Allowing the continuation of bots in eve online?
I think the real question you want to ask is bots making CCP more money than it is costing them to try and do something like this?
What is your point again?
