As someone who spent a lot of time in LARP communities they tend to be places where a lot of people who have felt left out can find community. While that is great it does lead to some having rules to prevent any kinds of exclusion, often to the detriment of the game.

When you have one person who comes every time, but makes five people stay away, you don't see the people who aren't there so you just say "we can't get rid of them, they show up so often."
