I’ve seen comment thief’s get rewards in past and it took other people to point out to the person who reward them that they in fact stole that comment.
It does happen from time to time especially when people self vote and mess up the order. I am sure I have been fooled often enough too.
Between this, spam, and all phishing going around. I guess it’s just showing of the platforms success. The higher the price goes the more of this we will have to put up since they don’t tend to just ban the accounts.
I am pretty sure this will happen and it will happen at more and more subtle levels so it will be more difficult to spot.
