That's the equiv of saying I don't need privacy because I have nothing to hide.

Just because you don't want anything to do with the type of people who would post pictures of you and slander / shit talk you doesn't mean that you should want that being out there to begin with - it's not like that sort of thing hasn't ever been weaponized against someone before.

The worst part is with this app there is a high chance you'd never find out that anything was ever said about you until the snowball is so big that it'll crush any attempt to slow it down.
