[Robert Chudek - K0RC]

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.
