pi network can be detected as fraud or not if it really already has the facts. however, until now there are still pros and cons with the pi network. some say scam and some say legal. this must really be proven in real terms before giving a statement about this project.
The proof will also be very complete if everyone can get to know the team that built this PI Network thoroughly, because without knowing who the owner is, it will also not be used as a reference for a scam or not, so this also needs to be researched before accusing it of being a scam.
