...see, I was puzzled by that too but I am not good with computer. However, if not even an AI can figure it out...
Since (AFAICS) he hasn't provided his public key anywhere, with which we could verify this message, then it's meaningless (as I understand PGP/GPG).
If he did so, then we could tell if any leet haxors had twisted his words behind his back - if we bothered to check, which we of course would not.
The comment links to keybase, and his public key is there. Not that that makes it any less pointless, but for what it's worth if you want to copy and paste his comment, remove the leading whitespace, and fix where the markup has mangled the signature, you can satisfy yourself that this comment was written by DarkLinkXXXX and no other.
Aha. I visited the site, but didn't see any user-info links; but when I put his hubski-username into the search-box, his profile and key did pop up.
I agree. That's why I moved my signature to an unmangled pastebin link. ;)
