I doubt he will get banned for this.

The server don't belong to them after all and the way Caravan was designed let me think they didn't intend to have only 1 party camp it all the time. ( sinve depending on how long it takes you to complete it, the next run can be open before the last one is over, letting new people join it.)

What I did n the past was annoying them to let me in party. If they didn't, next time join I warn them that if they don't invite me, no one get seals
