I myself use eQSl and not LOTW, as the hoops to jump thru and getting it all setup. I understand about the security they want for their programs. They(ARRL) are a authincated member of eQSL so it would seem that they should accept cards from eQSL. Now on paper cards, years ago before the advent for the computer in every shack, and paper cards were the norm, I received several cards for contacts I never made, this included cards when I was the DX. I sent the cards back and stated it wasn't me. There is always ways to beat the systems.
