But more seriously, if there are bugs that can reveal the poster's identify in the first place, then it's not anonymous. It's very easy to make your servers not record any identifying information along with the text or pic. It's also easily possible to strip any exif data from an image. Clearly for usefulness/monetary value, the identity of the poster is being recorded.
The identity of the poster is recorded as a core conceit of the system. The app/network is explicitly for sharing secrets between friends. It has to record and store who the secrets came from, in order to determine who their friends are and thus which users to show it to.
Before you even sign up it's quite clear that there can't be anything anonymous about this at all. It delivers plausible-deniability at best.
Their claims may be fuzzy. People may not be paying too much attention when they sign-up or use it. But they're quite clearly not trying to make an actually anonymous secret sharing site.
