Oh, nobody's going to post an open invitation, like "Follow this link." When we are finally ready to send invitations, it will be by email, the abuzz 'invite a friend' system, or as a last resort, something like 'Hey Fritz, contact me at
[email protected]' or something like that.
Of course, it's inevitable that some of the trolls will have human friends. When they finally show up, we'll see how they work out. The site is not without moderators.
