Say I were single and ended up being slandered on that site, what would happen? Sounds like the users on there are not the kind I'd want near me anyway.
There is no safe amount of attention from people who spend their time sharing 'drama' online. The most extreme example is the kiwifarms lolcow stuff, but even very normal and boring internet 'microcelebs' learn the hard way that some insane person somewhere will decide they don't like you and go out of their way to interfere with your life and relationships.
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.
Guess this is too theoretical for me to worry. This app was up for years, I was wondering if they ever coordinated an attack on someone other than just avoiding him.
And yeah, I am trusting certain companies like Apple with some of my data to some extent.
