Just passing by, please ignore me, I am currently not interested on this case as I have other things to attend, as well as not gonna draw any conclusion about
loginsam45, nor that I've ever have to verify a signed message, but tweaking with it a little, the error made on the signing message seems because somehow when he posted his reply, there's space between "eedc" and "e6e4", where it should be a complete line without any space. Not sure why when we quote his post it'll show that the line is uninterrupted, but upon being posted, it'll be broken into two line [the image I show will describe better]


This line, upon being pasted into
https://app.mycrypto.com/verify-message, will also have a space, as shown on
FatFork's screenshot as well as mine below, and removing that space will validate the message, as shown on the image next to it:

That said, and as I previously said that this is the first time I have to verify a signed message, so I am not well versed on this matter, I am not sure if the message should only be verified by "mycrypto" or if other platform will also work, but I try to verify it on etherscan as a doublecheck and it turned invalid,
