Wouldn’t it be awesome to have an open-source, decentralized database of cell towers—where data is collected anonymously and verified by multiple people? If a new tower appears, we know it’s a stingray device. 
I know databases like this exist however they can easily be positioned 
I’d love to build this, but I lack the time and energy to learn and make it happen. The platform should be fully decentralized, free from manipulation if a contributor is compromised the system still thrives.
