CanI suggest you read thoroughly the documentation on how the mode
works before making claims about the database.and validity. The
database can only be updated by stations decoding and reportoing, and
if each QSO partner has a reciprocal report in the database for
near-adjacent time intervals , then they MUST have been in contact
with eachother and cannot be classed as anything bu a valid QSO. Its
impossible to have achieved this in any other way.
Please read all the documentation first.

Hello group !
I am not an expert with WSPR at all. But I followed the discussion
regarding
false detection of calls thru the database.
To my understanding the WSPR operator has NO way to really find out
whether
the computer came to the right conclusion about the calls received, or
whether it just judged by means of plausibility. We humans have no sense
for
phaseshift, that means we have to believe the machine.
I think that the database in the background is like a walking stick for
the
blind.
Of course it's a new and exciting technology, but I doubt that it is on
one
and the same level with a regular exchange and therefore should not be
considered equally verifying a valid contact.
