Squad size from which leaving is penalised
Up to this member count, leaving a squad costs nothing.
scum.SquadMemberCountLimitForPunishment=2
What does this setting do?
SCUM penalises players who leave a squad in order to discourage squad hopping — constantly switching groups to harvest gear or intelligence. This value sets the threshold: up to this member count leaving is free, above it the money penalty and probation apply.
The default of 2 means leaving a pair costs nothing, while leaving anything larger costs money. That protects established groups from infiltration but also makes experimenting expensive — particularly for new players who do not yet know where they fit.
Which value suits my server?
4 to 6. Let players find out where they belong.
2 (default). Infiltration should cost.
2.
What to watch out for
The threshold alone penalises nobody. How harsh it gets depends on the money penalty per former member and the probation duration.
