I highly doubt someone would do this without some sort of payment / contract. Basically, here is what I am trying to say. Say your angry at your admin one day k? You get mad un-add him from the control panel and totally just kick him out. Not only is all his / her's work gone but now you have a fully functioning server. The reason anyone who does this would want a contract is so to prevent being un-added from the control panel and prevent being charged back the contract acts as paperwork should someone not pay the admin. Not saying that you would do that, but I've seen it happen a million times...
And if your intrested, I run a tekkit lite server for just around 7 to 8 people, its whitelisted and we don't have any item bans in place although we recommend users don't do certain things. Our current project is a "City" build where we are building a giant working city!
