The agony of the unknown. Forgive my ignorance of tokens, but if they depend on IP address then why would Sooloos stop and yet not a direct Tidal connection at the same address? And if it is some combination of IP address and MAC number, since MAC spoofing is rather easy that wouldn't protect Tidal's business well enough, I assume. I take it that there is something much more subtle going on to differentiate legitimate customers from fraudsters. How does it single out Sooloos kit from other things I own, and why?
