Nah, you are not a signature spammer. You are actually some one knowledge and helpful as I have read most of your responses to different topics around the forum.
I agree, and I also posted in that thread. Upon revisiting it just now, it looks like two members got defensive and it escalated way past the point that it should have.
You and dkbit98 are both helpful posters as far as I'm concerned, and I don't see any real issues you two should have with each other, though I understand you took offense to him alluding to you satisfying your "signature quote" (lol). I get the feeling dkbit98 thinks there's an extreme bias in the HW section toward Ledger products, and he was feeling just a little bit grouchy about that while making replies.
My suggestion: both of you bury the hatchet. You're both valuable members of the forum. And even if dkbit98 doesn't want to bury said hatchet, at least take the high road yourself and let it go. No harm, no foul. And the consensus seems to be that what he wrote about you isn't true.
