Unreliable might mean too hig, unreliable might mean too low, for sure unreliable means neither the pilot nor any speculations should rely on it...
The "...seemed to be going quite fast" observation is a reference to the "Flight Radar24" data, whcih is ADS-B data, derived from GPS measurements and is completely independent of, and unaffected by any problem with airspeed indications.

If your GPS reported groundspeed is is approximately 300 knots, a stall is pretty unlikely.
