Side point, I also don’t use social media app but at this point it doesn’t matter. 3 of my friends sent me my faceapp photo. No way to escape this.
Of course, to do it well, you'd probably want to start doing it before anybody submitted your real photo, then just submit a fake picture at random intervals for perpetuity.
An alternate variation on this is flooding them with fake people and fake names to make their real database worth less.
