If the glideslope signal is fluctuating it should not be used. ATC should switch it off.
Well the autopilot doesn't think it just follows the signal whether it is correct of false... A pilot who has some common sense (and it seems a lot of them don't), who is tracking a G/S with a regular rate of descent on a stable approach will not all of a sudden, if he is competent, simply push the nose hard over to follow a G/S towards the sea especially if he was warned twice by ATC prior to the approach that there might be some problems with the G/S.
