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.
Please note that all the plagiarised content was posted in the gambling section, where I didn’t even know it existed, let alone read it or merit it…
Any other content I merited on both profiles wasn’t plagiarised, at least to my knowledge.
Enough for this, let’s not derail too much this thread anymore.
