Don't put pillars and get boobs putting half a thatch box just outside your doors with fences blocking your pathways. Don't put pillars and say bye bye to caverns because some guy who shows up once a week blocked it thinking it was his own to enjoy.
People do it for a reason. So they dont have people building right next to them. They dont like having to spend the whole time loading on and unloading bases. Gets to be a pain in the ass.
I've seen people be dicks and build a wall completely around other peoples bases before so you better believe the entire area around my base is pillared up, it's an anti-griefing thing
