Now I have generally refused to use someone else's material when creating some kind of guide, only my own research.
TwitchySeal, see what he said. It means he does not continue making these posts [posts articles and don't give credit to the source].
I think it's pretty obvious why he stopped quoting articles without citing sources (which it looks like you, too, are guilty of), and it has nothing to do with being a merit whore.
I checked his history. He still starts long in depth threads on a fairly regular basis, just like he did when he "needed" merit.
The feedback was left one and half or more years ago when it was a fact, at that time he was earning all those merit by [1]making topics without giving credit to the sources [2] spamming the reputation boards with his self praised topics [3] there were many other evidences of his merit whoring. The merit whoring was obvious at that time.
What's obvious is you don't like the guy and you do like creating drama.
He puts efforts into his posts and he doesn't scam people. That puts him in the top 5% of posters on the forum imo.
