The app stores haven't pulled it because they are waiting for this to flow out of the news cycle and reduce the impact of this subset of our culture freaking out at them.
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.
And yeah, I am trusting certain companies like Apple with some of my data to some extent.
1. Wrt/ dating, the obvious downside is that your potential partner is dissuaded from dating you because of what is said on the platform.
2. I can also see vigilante justice; an extremist reaction to what is said on the platform. Actual violence, or just harassment, online or real life.
3. Or, I can see corporations using these databases on the down low to filter potential employees, similar to how they screen online presence as well.
Of course, all of these are just potential risks, not things that actually happen(ed yet).
