PSA: No triple stardust for feeding berries to gym defenders.
Sorry to fellow city players looking for another use for those excess Pinaps.

Why not both? I tend to farm dust in an area that has a good density of spawns and stops. Usually, I'll manually spin stops, let the Go+ catch most of the things, and I'll manually catch wild evolved Mons (that are likely going to run if I let the Go+ try for them). Once my bag starts to get full, I'll start dumping berries into gyms while my Go+ continues catching things.
Has someone hacked Mr-ex777's account? Normally he's a jerk, yes, but this is just wwwwwwwaaaaaaaaaaaaaaaaayyyyyyyyy beyond his normal jerk attitude to the point where I don't actually believe this was written by Mr-ex777.
Mr-ex777, if you're out there and locked out of your account, make a new account and let the admin's know that someone has hijacked your account before people start to believe this is ACTUALLY you.
If I'm wrong and this is actually you, I would suggest you go to Google and type in "Anonymous Mental Health help line in" then add either your city or the nearest large city to where you live and use those results to find someone who can help you figure out how to repair whatever has broken inside your mind.
