Kris,
You cannot determine fake QSOs on LoTW. That is because the confirmation
is not 'validated' (made visible to both stations) until both
participant's log entries match.
The eQSL system works differently. Incoming QSL requests arrive in your
"inbox" whether or not there is a matching QSO on your part. This is
just like QSLs coming into your postal mailbox. You can accept, ignore,
or reject individual QSL requests manually, if you wish.
As a side note, the eQSL system came in handy when I was processing my
old logs. In the early days, I had been logging my QSOs in local time
instead of UTC. And with the different on/off dates of Daylight Saving
Time, I was able to determine that my conversion to UTC for some
contacts (and sometimes whole contests) were wrong. In that case I would
see a dozen or so eQSLs that were off by an hour (or sometimes 5 or 6
hours). I was able to correct my log, delete my bad records from eQSL,
and upload the corrected log. This process is not possible using the
LoTW system.

Larry,
I'm curious how to use LoTW to determine if I have any fake QSOs
against my call.
Can you elaborate?

I upload to both LoTW and eQSL. I have gotten a few "fake" QSOs against both
my home call (130K QSOs) and my XV calls (3W2NWS - 5K QSOs - and XV2W -20K
QSOs). Most of the fake ones were for my XV2W call and for a time I was not
in XV. In total maybe 15 fake QSOs.
Confirmation rate is nearly the same (within 1 per cent) for both LoTW and
eQSL at around 20 per cent overall for my home call which has many QSOs
before 2003 (roughly the start of LoTW and eQSL).
Confirmation rate for my XV2W call has recently changed with LoTW now around
37 per cent and eQSL around 28 per cent. These used to be much more like my
home call in range and spread between the two services. Paper QSL rate is
about 25 per cent for the XV call. There is overlap in these numbers in that
some stations are confirmed in all three categories (eQSL, LoTW, paper),
some in two categories, and others in only one category.
There is a difference between continents for my XV2W QSOs. NA is decidedly
more LoTW oriented with 52 per cent confirmed LoTW vs 22 per cent eQSL. AS
OTOH is 32 vs 22 per cent (LoTW and eQSL respectively) and EU at 38 vs 32
per cent.
