Gyms are unplayable in my area now.
Multi-accounters in my area are abusing the Network Error glitch after a raid to prevent attacks on their gyms.
Every time their gym gets attacked, they use a different colour alt to attack the gym and sabotage the attackers. They even go to the extent of creating alts to do level 1-2 raids at their gyms for this purpose. The worst thing is, some of them live on top of gyms, and they can easily disrupt attackers from the comfort of their home.
This is insanely hardcore for 50 coins a day.

Yes, I forgot about the alt part. But,
1: If I report the whole group, I’m assuming that all of them are using this exploit. This may not be the case. The rest of the group might not even know that one of them is doing this!
2: They may not actually be spoofing. It’s just a possibility, even though I think it’s not likely. And the TOS doesn’t forbid hiding up high rise buildings.
They do it to get coins. They are the regular players in the area, and some of them even live on top of a gym.
I’m not really affected by it as I can go to other areas to get my coins, but it is worrying enough as if this becomes widespread, it can make gyms unplayable everywhere.
GRBs can only stop players from taking down the defenders. It can’t stop players from attacking non stop to farm their gold badge. This glitch can stop players from farming their gold badge as well.
Huh, this is an exploit I've never heard of until now. My advice would be to report the situation directly to Niantic, and be sure to explain exactly how this particular exploit works. Be as precise and detailed as you can (how to trigger the glitch, how long it lasts, who is affected by it, etc), so they can understand exactly how it's done. There's no guarantee that they'll do anything about it, but it certainly doesn't hurt to make them aware of the issue.
