Infamy is as elusive as fame
Notoriety is elusive. If you write scandalous posts, treason or incitements to revolution, your chances of achieving that elusive infamy are slight. Only the famous or socially connected can achieve infamy easily. Yet again, the odds are stacked against the common man.
The only way forward might be to exceed all previous crimes in your chosen category, murder, terrorism, fraud etc.
Maybe you should go for it and score one for the ordinary people?
Or settle for being a local eccentric, if hurting people is not your thing.
