What constitutes "soft antag rolling"?

How long is one expected to play in a round before they are given leeway to abandon their role? Furthermore, are passengers held to higher or lesser standards in terms of leaving their roles mid-way through round? Are they expected to stay passengers, never ghost, and play the round out every single round? Is suiciding/ghosting after 5 minutes in and of itself antag rolling, or only when it’s done in excess? Is there a limitation/quantifiable model for “antag rolling” or is it solely at the discretion of the observing admin?
