How can you forget you replied and post the exact same post?
I was thinking about the times my browser crashed, and I had to start typing my post again. I can imagine overlooking a post that went through that way.
It's just pure lazy sig spam. Not much different than copying someone else's post really and if you see his feedback from yahoo it's not the first time he's done it (though he's deleted that post). If you go through his posting history you'll likely find more but they're all one/two liner shitposts anyway so I don't think he deserves any mercy here.
He didn't have red trust from yahoo yet when I posted this (yahoo refers to the same 2 posts).
I agree he won't be missed.
