the anti cheat system is really solid right now... everything of what you said is unsafe...also they start to ban directy without 7 days now.
I suppose at this point that you could use the trainer with secondary accounts for farming coins but it's also very risky to transfer coins from one account to another lately so I don't really recommend it.
Any idea how safe it would be to use player info and instant dc (so I could disconnect against better players)?
Is that also unsafe?
