Just tried and it seems we have an underdog here that could be useful to avoid spammy results. I can totally see why they want this to be invite only, as they probably need to find out how to scale well. If it would go viral suddenly, they might not collapse and the whole effect would backfire.

Edit: This is really promising and interesting. They show a summary of the link when you hover over the crystal ball icon next to it, together with a button for "Block" and "Boost" - i.e. you can vote with your account. These metrics could be used for ranking and kill affiliate marketers.
