First mention of it was, surprise, a troll post egging on someone who posts in monero threads, just like many other times a thread became about Monero:
I see you Monero community have a two-faced logic system because you can't walk your own talk:
Who is forcing you to respond in this thread?
Nobody but yourself.
Do us all a favor and at least own your own actions (like wasting your own time posting on the forum per your own words).
So when you come back over and over and over again, blaming people for wasting your time, it's their fault you're posting, right?
