Less gaslighting.

There's a lot of ground between "error messages precise enough to effectively give botters a to-do list" and "faking failures 100 times in a row." What was the marginal utility of the 99th fakeout? Are there really enough otherwise effective bots that get persistently tripped up by this particular fakeout to justify sending the poor kid crying to his room?

Almost certainly not. What really happened is that someone removed (or never added) user communication in order to maximize their score against botters and gave little thought to mitigating their false positives. Minimizing them, yes, mitigating them, no. "Humans are smart, they'll figure it out," they rationalized to themselves, and called it a day. They never bothered to calculate (or even guess) when the marginal utility of the fakeout dropped far enough to allow them to have mercy on the poor humans still caught in their web.
