Yes, LotW has the capability or rejecting duplicate QSOs - but not
until the QSO has been checked to see if it is already in the database!
The most "expensive" part of the entire LotW process is checking to see
if each QSO in the upload is new or has already been entered into the
database.  Thus uploading QSOs that have already been uploaded consume
significant amounts of processor time - which before the new hardware
was responsible for causing LotW to be unable to process all of the new
logs it received.

Even *six years ago* the LotW staff requested that users *not* upload
duplicate QSOs.  That request is still on the LotW User home page:

Unfortunately, WriteLog (and many of the other contest software) does
not use the tQSL "date window" to sign only "new" QSOs.  That is only
logical since there should be no duplication in signing QSOs from a
short duration contest - but the assumption breaks down when singing
the "general DXCC tracking" contest repeatedly.  One would hope that
Writelog would store the date/time of the "last uploaded QSO" in each
log and use that as parameter to limit uploads - or add a hidden
"LotW_QSL_SENT" field, set it to "Y" when uploading a log to LotW,
use it to prevent uploading duplicates and include it in exports so
other software does not upload the QOSs as duplicates but those are
not currently available.
