Initiative: Own Page Visible to Post or Vote on Others
I'll often click on the author of an appealing or more significantly, controversial post and find their page is not visible. This seems one sided and unfair when the post is about another bigga. There are plenty of other privacy protections and one does not need to be visible to purchase or make reviews so I don't see a lot of downside here.
When you make any post you are speaking in public. I don't see why your other public statements should be hidden, they are also public statements. As for others statements on you that is a primary mechanism of accountability here. Is there anything else on the page?
I think just a switch, close your page and then all your posts across the site are invisible so if someone has a panic they have this control switch. I'm sure that it can be abused but it need not be a permanent also a kind of throttle.
I think all the resistance against this is really 1 thing: people don't want to get posted ON, they don't want to be the subject of posts because it doesn't seem to have much utilty besides getting trolled on.
