LoTW doesn't know anything or care about confirmations in your log.  All it
knows is the callsign, date, time, band, mode, etc. of the QSOs you made.

There is no such thing as "accepted".  All LoTW can do is match QSO information
in a log YOU submit with QSO information in a log someone else submits.  If
there is a match, the QSO is considered "confirmed".  Your QSOs must be signed
with your private key, and the DX station's QSOs must be signed with his
private key.

In simple terms, you tell LoTW something unique about a QSO you had with a DX
station.  The DX station tells LoTW something unique about a QSO it had with
you. If LoTW decides that you are both telling the same story, then it
considers the QSO to have happened.
