I thought the first ban would be 7 days, not 30 years..
Any opinion on this?
Well, anytime you cheat, there are going to be possible consequences. Cant be one to complain about getting banned or for what length of time if you are doing something that was not attended to be possible by the developers. You take a risk using any trainer, mod or hack, and if you do, you gotta accept the consequences. No one is forcing you to cheat or break the Terms of Service.
