We do not have a zero-tolerance policy in Euro Domination. We distinguish between one-time offenders and serial offenders. Serial offerenders are permanently banned from all games. One-time offenders are permanently banned from the game they got caught on, and temporarily from all other games in the period directly after the ban.
The reasoning is as follows. There are (a lot of) kids (and grown ups) who actually learn from their mistake. Getting banned for life from one game has a big impact on these people. They are named and shamed in public. Compare it to crimes in the real world: you don't put someone in prison for life for shoplifting. Instead, you punish them accordingly.
Those that haven't learnt from their mistakes will be caught again without a doubt. Serial hackers are treated with zero tolerance by us. But think about it, imagine I hacked and got caught once 10 years ago. I would still be banned under zero-tolerance policy. These kinds of laws are only applied in countries such as Iran :)
