We have rules. It Ban times change due to many different things, One being how popular, if there committing other offences, Just because they've been banned for ramming doesn't mean they didn't drive reckless, or on the wrong side to do so. So it changes with every situation we approach, also if they have previous bans for it. But as for a name change, they get 3 warnings as the post above said, if they fail to do so then we can give a ban depending on there name, But still if they have been banned for it before or another offensive name.
