Of course you must handle feedbacks if you are posting on a blockchain, also the negative ones, and nobody was complaining about your downvotes, so they can handle this of course on their own.
I just saw the downvotes and found no reason for that, so its only a general discussion.
Downvotes are negative feedback, but discussion first is usually the better way of giving a feedback for content you dont like, in my point of view.
Best regards.
