The submission for THATDAY.EU presents significant red flags, including unverifiable traction claims ('most people have used my product'), irrelevant metadata (listing 'games' as technology), and invalid contact information. While the product category (menstrual underwear) has inherent utility, the project appears to be either abandonware or a low-effort test, with no detectable digital footprint or market presence.
