This imo is a great idea in theory but I am not sure there are enough in the hive community that tout the ideas of anti-censorship would actually be willing to put their necks on the line for truly unpopular or controversial views that they would support such an endeavor. I can already imagine the users grabbing their pitchforks when they receive downvotes to neutralize the upvotes of a malicious downvoter. I could be wrong though.
