I don’t believe regionals are the reason we have spoofers. Spoofers are here because they are lazy and don’t want to go to the trouble of going out at all, and with spoofing they can get more/better stuff then the normal players. When the game launched there were places you had to be to get the best Pokemon (Santa Monica pier anyone?), but that was for 99,% of the playersbase a no-go. People didn’t spoof there for the Tauros, they spoofed there because that was the spot to be. That and just lazyness.
That said, i do believe the sheer amount regionals we have now compaired to earlier is causing some new spoofers. In my community we never had spoofers, now already 4 admitted (or got busted) to have a spoof account for the regionals. But those players get what they want and go back to normal play.
So IMHO the real spoofers: just lazy
On topic though:
the game is over 2 years old, the hype is long gone and sponsored areas don’t attract as much players as before. I’ve had a sponsored mall on a 1-hour drive away, even had safari events there. i’ve been there only once in all this time. And players that live closeby won’t go tourist shopping there so why sponsor then? It’s the Niantic events that attract players, not sponsored stuff
