How can I check if I was detected as a Cheater?

[Anxious]

As the website PokeAdvisor.com is down I really dont know where to check

[noobcakes69]

I'm pretty sure it's based off your stats, like pokestops collected, pokemon caught. Check medals and see the stats there.

Why exactly does it matter that a third-party website flags you as a cheater?

They get the data from Niantic server.Who knows if the account marked as a cheater will be banned or sth else?
