Don't just get rid of jail, use both systems, jail the high offenses like hacking and ban the lower stuff like cussing. Using just one system isn't gonna work due to either being jailed for something minor or only getting a measly ban for major things. Also, make a written set of punishments for certain offenses so people who only deserve a ban don't get jailed. This isn't supposed to be for anyones benefit, people need to be punished according to how bad their crime is, giving minor punishements for major things won't help anyone and vice versa
