Only banned once or twice. That said, always had a very clear policy following Wheaton’s Law (“Don’t be a dick”). People know when they’re being assholes. If they’re being assholes, they need to be somewhere else. This is a private party and if you piss on the carpet, you will be escorted off the premises. The clearer that is, the fewer people seem to feel a need to test limits.
There are a few people whom I’d ban on sight. Those are the known predators who have a history of causing game meltdowns or driving away vulnerable players. I wouldn’t invite a known predator into my house in real life, either.
On the other hand, a few people who have been problematic elsewhere, have turned new leaves on Keys and never caused trouble. Sometimes, people do learn from their mistakes and just need a fresh start.
The most arguments I’ve watched around banning and behaviour were on games where game policy was three pages long and waffling. The shorter and more concise it is, the less attempts to rules lawyer out of trouble. Because people do indeed know when they’re being assholes.
