Ah, so it's considered a "bot" because the game is expecting something to reach the display before a human responded? The card isn't doing any network input, so something must be checking if the state was blitted before the human response...(?!)
It's not considered bot or anything. It's just Valve forbids any software signed or unsigned to mess with game executable, data or memory without being specifically whitelisted.
Why? Because even if software doing this is legitimate it's can still be used by actual cheaters by patching it.
