We had a gym purge locally, last ight. A load of yellow gyms had built up to level 10, during the week, but this morning, they were still level 10, but with only a few pokemon in.We plonked some of our finest in one, and it filled up again, behind us.
Then went up to another town, this afternoon, and it was full of grey, empty gyms. We had fun gettign into some, but didn't stay in them long enough to profit from any of them, as we'd already claimed for the two we got into, in the morning (e took down a small fym and I put a ditto into it because nothing ever stays in that one very long!
All the obvious level 40 spoofers in Gateshead are still in situ, mind. I took some screenshots, the other week, so might flag them up.
DS1 has been grumbling about not having had an upgrade, yet. I got my 5th, this afternoon! I might end up throwing some out because I can't do anything with them.
