I wanted to start a bounty and I thought of getting to the unanswered ones. This one in particular is where I placed it.
I waited for a while and no one still answered, so all that was left for me to do was to answer it. However, the answer is basically copied from a MathOverflow answer that was actually mentioned in the comments of the MSE question.
If you take a look at my post, it gave credit towards the original poster, so this likely means I'm not a "plagiarizer", but it still bothers me that negative results are the income (downvotes, deletion, made community-wiki while I have a negative score).
At this point, I'm wondering if this is even allowed. Is it though?
