Detecting Bots
The idea is not new, having some sort of captcha system to detect bots.
But instead of placing it on the logging or queue screen, I think it should be placed on the, let's say, 5 initial seconds of a match.
A player would be asked to answer some question, click some randomly placed button, or interact in a certain way with their teammates. If reported as bot, failing the captcha would give a strong evidence of cheating.
