i think you will be reasionable safe aslong as you DO NOT use the dupe trick, i was sort of in the same position as you did the dupe and got banned

i was getting sick of the game anyway so i didnt actually care that much. But be warned with that one, your 99.9% likly to get caught.
Macros and bots are reasionable safe to use, NC dont seem to do anything about it. Just be careful were you use it and you will be fine.
As for scamming i have never tried it myself, but i think if you get caught doing it you could face a ban so be careful with that aswell, its hard to scam proply though now because most people are clued up about it.
