Remember that discussion about huts around a guys base? He had the pictures of it, and I would say one very good argument for that land claim on a PvP server was to keep enemies from building right on top of you.
You adamantly argued that its against the rules, and people should not do that. Ok fine - you just opened the door for players to build right beside each others land claim, so close that your original post here is exactly what happens as a result. You reap what you sow.
