The "misdemeanor trespassing" is understood by everyone - basically, you're choosing to be banned, and if you come back the cops will give you a nice little ride to the station and then let you go.

Similar things in the digital world would be the ability to lock your iCloud account so you couldn't download gambling apps, and if you want to be unlocked you have to send a notarized letter to Apple and wait and reply to a confirmation letter. This adds delay and makes it so you can choose "not to be tempted" in your right mind, and when you're desiring "the fix" you can't get it right away.
