Damn! I sent 335 merits to acquafredda and 87 to Karartma1, for a total of 422 merits to banned users out of 459.  92% of merits to those two profiles only.
I reckon he was a very knowledgeable user, and I don’t know why he plagiarised content on the gambling section (where I have never set foot). So I think the merits I sent were done because he/she wrote something useful, but I am so upset about this lack of respect to the forum community…and made me top a chart I didn’t mean to.
