Granted. With the exception of the AVIONICS SMOKE warning, all of the other ACARS messages, if not daily occurrences, are certainly observable from time to time and don't typically result in the subject aircraft falling out of the sky.
The ACARS don't appear to be real, to me
That doesn't follow. The fault codes quoted match the error messages - they could be genuine.
