Recently all Niantic seems to be tweeting about, is that they are currently working on bugs that range anywhere between login issues to Gym defenders Pokémon being forcibly kicked out.
A while ago a nasty bug was found and reported by the members of the Pokémon GO community.
Abusing this bug will give you infinite PokéCoins, yes that’s a possibility and it’s been notified to Niantic Team members, it is not clear how long they might take to make an official response. Basically what’s the big deal is that changing the time zone to another day will reset the daily limit on the coin collections from gyms, it can be used an infinite number of times per day without any consequences (At least as of now.)
We know this is bonkers, let us explain it to you, today’s Tuesday 18th July and you have already received your 50 Coins defender bonus that is the maximum allowable for a day. Let’s see you got a few more Pokémon defending in gyms and you want to mine coins from them as well.
All you gotta do is, go to your Phone’s setting and manually change your time zone to a place that is on a different timezone than yours. In this case, it would either be a Monday or a Wednesday.
Once you have done that, wait for your next defender Pokémon to come back to you. You will see that you will receive 50 coins instead of the usual number of coins that you receive. This can be repeated a countless number of times per day.
It is possible for Niantic to track such abnormalities with relative ease. Even an amateur programmer can write a simple script to read the Gym coins file and check if they received more than 50 coins within the past 24 hours. It is unknown when this bug was first reported, so they might have to run this scripts on data collected over the previous week as well.
I’m positive that Niantic will make sure to roll back all fraudulently earned coins. Seeing as they can’t undo purchases, they will be leaving many cheaters with a negative balance. They’ve already done that once in the past.
What shocks us the most, is that why was this exploit left unchecked during the gym rework testing phase. They should have known it back then.
