Photostovis addresses a valid problem (privacy-focused photo storage) but the project appears to be a dormant hobby initiative from roughly 2013-2015. The submission contains significantly hyperbolic and demonstrably false claims regarding traction ('most people have used my product') and vague financial metrics ('all time marketcap: 500000'). While the underlying technical concept of a C-based server with real-time rescaling showed promise at the time, there is no evidence of current active development, mass adoption, or business viability.
