At least a banned account can still lurk without any of the restrictions you face when you aren't logged in. It's what I've been doing.
And yeah the hacked app was probably what got you banned. Heard it quite a few times. Might not be because of the app itself but because your modified version messed with Reddit's device fingerprinting and you got flagged as being somehow related to a large number of other banned accounts. They've cranked the ban evasion filter up to 11 in the last few years and it's insanely easy to get flagged now.
He really wants to make a new god game huh
