If you don't want your comments hidden - don't say shitty things. It isn't a hard concept. This also applies to being banned.
If only it worked that way. Not every comment is shitty from people, for example some could just be a user disagreeing about something etc ya know a difference of opinion etc. Also some people just follow users around and down vote them no matter what they say. And then you have supporters who have twice the down votes. The system just doesnt work as it was meant to so id like to get opinions on what people think could fix it and imo thats removing the down votes as the ones getting up votes would still go to the top and mods can remove the "Shitty" things people say just like how they ban people for shitty things.
