I know some people maintain their innocence when accused for hacking or exploiting bugs, and maybe some of the bugs are responsible for the said ban.
I can personally give an example of a bug that probably could have got me banned if I maybe hadn't of made a ticket asking WTF was going (it never got answered so abandoned it). I'll try and remember exactly what happened although it was a few weeks ago, but thought I'd share what happened.
If I remember correctly I was idling in UC and got a DC, or the server crashed. Before this I was in grom'gol and got the zep. When I logged back in, I was on a flight path, but was flying in a weird way. Going underground and straight lines, rather than going around the world. Now bearing in mind I didn't have hardly and FP's linking me up from north to south and I didn't know where the hell I was going, but this erratic flight path putting me underground and flying through mountains and shit could have quite easily flagged me up!
I had no idea where I was flying to, as when I dc'd I was just idling in UC like previously said. This phantom flight took me all the way back to grom'gol and dropped me there. So yeah, thanks for me wasting 10 mins getting to UC via the zepp lol, even stranger though, when I looked at the flight path when I landed, I still didn't have the taxi points joining me from north to south, so had to jump back on the zepp to get to UC again.
TLDR;
Maybe some people don't even know they're "hacking" as it could be a simple glitch like what happened to me.
