Not to defend it, because I think it's a terrible and alienating idea to bar members from entering your FC house until they've reached a certain rank, but there ARE perks inside a FC house that "leeches" could theoretically abuse. The vendors you can put there are awesome, and I could easily see a crafter joining a FC SOLELY for the purpose of accessing their vendor.

Of course no matter how antisocial the leech, the very act of crafting contributes company points so it's not really feasible to be a TOTAL leech. Also, having someone access the vendor doesn't actually cost the FC members anything.

A way people COULD cost an FC actual money is joining them in order to eat their food furnishings. I find it hilarious, though, to contemplate anyone being paranoid enough to believe someone would actually join a FC to eat their furnishings. XD If it did happen, I'd imagine it would be an actual targeted attack against the FC; someone from outside the FC who has a grudge or something... They fool someone into inviting them to the FC, and then they DRINK YOUR MILKSHAKE! THEY DRINK IT UP!
