CCP cant do it that way for legal reasons.
That isnt enough evidence.
Sufficient for internal flagging for review, perhaps, but not enough for an account ban.
Also, not all bots run all day, or everyday of the week.
Some also move around.
Im not going to go into specifics, but detecting bots is not as easy as you might think.
There are extreme options such as CCP logging and crunching the enormous amount of data sent by player activity, or outsourcing crunching of that data to a 3rd party, but those also carry some pretty severe/questionable legal issues.
I think CCP also has problems with how data is sent/received. Not all bots “spam” commands, some issue them once in the ~1s delay allowed for in the EVE system. This makes it difficult to differentiate between a human playing really hard (whom sometimes also spam commands), and a bot. This is barely scratching the surface of this and other complications.
Hence, as I proposed above, implement a system that prevents rudimentary bots from operating in the first place, which should comprise most of the bot volume.
A simple captcha, of some form, will wipe out most bots.
After that, CCP can focus on the remainder of more advanced bot systems, or those to which the captcha system cannot be feasibly applied.
The price for that we pay as players, is having to make a few extra clicks.
We make hundreds if not thousands of clicks per play session anyways.
Whats a few more.
Im ready to do that. I think most of you are too, if it means we cripple botting in this game we all love.
