Calls for air support are so common on our public Facebook group. It happens many times every day.
Spoofers are welcome as aid for raids by most people here, if they don't do any of these 3 things:
1: Use dirty tricks at gyms e.g. shaving, hogging gyms by spoofing
2: Promote spoofing, or encourage legit players to spoof.
3: Show off the Pokemon they catch by spoofing. A few spoofers tried to show off their Raikous or Enteis from "overseas" on the Facebook group, but were using wi-fi or mobile data from a local telco.
I'll be honest: I've called for air support on Facebook before at 2 Tyranitar raids.
