When should behaviour outside a community have consequences inside it?

Source: When should behaviour outside a community have consequences inside it?, by Matthew Garrett

communities don’t exist in a vacuum. They’re made up of people who are also members of other communities, people who have other interests and engage in other activities. Sometimes these people engage in behaviour outside the community that may be perceived as negatively impacting communities that they’re a part of, but most communities have no guidelines for determining whether behaviour outside the community should have any consequences within the community.

Did the behaviour violate the law?

Did the behaviour violate your community norms?

Did the behaviour violate the norms of the community in which it occurred?

As a result, communities struggle to make consistent decisions.
