This is the first time I read about this 'protection' mechanism. I don't see the difference between an account with rep higher than 65 and one lower, hence I believe the described behaviour needs to be removed. Or at least, the rep level need to be changed to a lower value. I've seen accounts with higher rep than 65 abusing Steemit, and I'm pretty sure this had nothing to do with a stolen account. My argument to remove this to me strange behaviour is that when someone miss-uses an account, it shall be made invisible regardless of rep. The question we can ask is "shall the UI enforce hiding of accounts/posts/comments when it gets downvotes?". I personally believe it shall be configurable by the user since many of the community members are in favour of freedom and why shall the UI then hide posts/comments when it gets downvotes? Just make clear it got downvotes, maybe with an icon so it is quickly seen? On the other hand, I understand the hiding feature of the Steemit UI, it ma prevent abusing posts and comments to get more rewards.\ which effects the reward payout distribution.

BTW, don't you think we should debate another topic on downvoting? The weight the votes gets based on Steem Power? Although I never run stats, I have the feeling (some of) the early adopters of Steemit who gained a lot of Steem Power and Rep over time, may misuse and abuse Steemit and nobody is able to do something against them, we simple have to little Steem Power abuse fighters in our community, while we for sure have to little high rep accounts that fight abuse.
