Fake GPS + 3 accounts users...

Dude, cheaters also have youtube channels.
Even they get banned regularly and they just make new accounts OR Niantic doesnt care shit.

Either way, cheaters win, always. (it seems)

Situation is even more pathetic cus those cheaters can propably make money out of it, they have fans like any other youtube channel.

I bet cheaters who has youtube channels doesnt even care the game itself, they only do it for money.
So they are kind of smart.

Anyways, as long cheaters have youtube channels, as long there will be ppl cheating.

if its the same 3 then it could be that he has 3 different devices or just 2 then swaps accounts. spoofers dont get banned unless ur really dumb with it but its still unlikely that they will get banned since niantic cares more about taking down bots than anything else. You could always join the dark side and enjoy the benefits it has to offer lol :).

Welcome to the club, Ive been dealing with this for months. Im a level 35 and cant even hold one gym by my house or my work which is just down the street. Every gym about, 30-35 of them, for 10-15 miles around me are all spoofer owned. Its worse now then it was last month and its seems to be getting worse.
Lately I cant load the game on android at least since the Christmas update. Sometimes I try 20-30 times and ill get the same frozen green screen. Ive found that if I turn off GPS it usually works after a couple tries. Anyways Im hoping that Niantic is testing something with the GPS to ban spoofers. Maybe its wishful thinking.

The key to holding gyms is to find spoofers that are on the same team as you.

Report the usernames of the cheaters to Niantic. It has a tool to do this. I experienced a similar situation. I reported it to Niantic. About three months later, the cheaters seemed to disappear. Maybe Niantic banned them only after enough reports came in. So report them. That is about all you can do, except quit playing in disgust.

No matter what Niantic do people will complain.

When Niantic really cracked down on bots and stopped jailbroken mobiles from working everyone complained that they were not adding any new content.

Now new content slowly gets added and everyone realises how bad it is with spoofers and bots around and complain about it.

You cannot win.

All I know is a few months ago something similar happened to me, I reported the users as spoofers and botters. I received an email from Niantic saying they cannot disclose any information about said accounts.

The next day they 6 accounts I had reported were all gone and I have never ever seen them again.
