Seriously, if that jerk keeps flagging me, I might stop blogging altogether. If whales are allowing this abuser to flag legit posts so he can upvote his own shitty comments to rape rewards himself, I don't know what motivation that leave to us.
Nobody is Allowing this, this is entirely up to one person and only they can do anything about it. If you base your success on what one person does you definetly invested in the wrong platform.
Whales can devastate an abusive user. While they are certainly not required to, their reputation should be worth enough to them that they might be inclined to act. Either way, if they want people to keep striving here, it's in their best interest to take action against assholes like this. As for your success comment, if you have someone consistently destroying your post payout--a payout that supports a large number of projects and people--where is the incentive?
Somewhere else, somewhere that guarantees a payout, or align your incentives in such a way that it guarantees payout here (donation/subscription) and especially in not allowing one person to dictate how and why you should post.
