I've got an account that I made when I got banned that I levelled to 24 Notting and sniping. It's not banned, yet
I also got all my money back from Apple that is spent.
I did an appeal when I heard it was a ban, but before I did I submitted a support request for not being able to log in. Niantic haven't actually told me I'm banned though.
How the fuck did you get 24 so quick? I fuckin' hate that I live nowhere near a huge swarm of Pokestops!!
I got soft banned as I appeared in Sydney whilst setting it up, didn't realise, and basically warped back to the UK.
