The more I think on this, the easier he got off.
He used an 'infinite shield' hack, so it's possible that he rushed through getting obscene amounts of money doing as Distance speculated [Thanks. Would +Rep you for that, but apparently can't. I hadn't even considered that before.] and leaving turreted weapons live in a CZ and going AFK. While he is "Shadowbanned" he could easily be doing the same thing. Either way, he has also let slip that he has at least one other account so he doesn't have to be isolated from the playerbase, he can be straight back in, using the same software that must be on his computer and therefore available for any account played on that computer.
.
FD have proof of his cheating, he ought to get a save reset an minimum because he cannot prove that he made whatever money and assets he has 'legally' within the game mechanics. I severely doubt he has and discovery tags on that account, because that takes effort and he doesn't sound like he can be bothered, but yes, everything should be wiped so he starts with a brand new commander, the prefix [CHTR] not [CMDR], 500Cr, and a stock sidey. AT MINIMUM. No excuse for using external software to modify the game, can't be done 'accidentally', no reason to believe 'education' will sink in. Save wipe or permaban.

Heck, I've done nothing wrong, yet I've not played in well over a week and it's not troubled me to do so with only a single account. Why should a week-long shadowban bother a confirmed cheater with more than one account?

OK, if he's only been doing it for a day and got a week ban, he might think twice, but who here believes that's the case? He could have been doing it on multiple accounts since Beta, and if this is the first time he's been caught, he probably thinks it's a lower risk that playing a pirate in the game.
