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.
In fact, there is nothing wrong with that. The task of any merit source is to evaluate useful posts and ... that's it. We do not guarantee that the user to whom we have sent merit will always adhere to the rules. I believe that it is worth worrying only if you sent merit to posts containing plagiarism. Then you should work on your attentiveness and more carefully check the posting of users before evaluating it.
Yes, it is certainly a little disappointing that the users to whom we sent so many merit ended up being banned, and it seems like we wasted a lot of the merit that was entrusted to us, in vain. But who can predict this? If you are an active merit source, then anyway, sooner or later, someone to whom you sent your merits may be banned. You can treat this as a normal expenses of forum life, where some users, in view of violation of the rules, leave this place, even though their posting was more good.
