I play 100% legit and a few local mystic players remotely take down lvl 10 gyms.... Then rebuild lvl 10 mystic gyms with noone there. .. I dont think niantic cares ive reported it. .... Offering fg for help i can buy more fg if needed

Sadly there's nothing that can be done. Wish I had better mews

Niantic seems to be looking into this problem, in general, before allowing trading, but they arent very vocal about it.
they also double in staff so... idk. enjoy the little things
