they ban them but unfortunately they always just make new ones, there was a new wave added with the the whizbang expansion that brought a bunch of them after that video was made, I don’t know if it’s as much as a problem on EU servers as I play on NA, but I played the game actively back in 2014-2016 and it was really nothing like this, almost all my matches are against bots at this point
edit: Bot Ban Update--Late March 2024 an interesting post if you’re curious how bad the numbers were, it’s improved slightly more since when I last posted
