They claim it will be decentralized:



The whole thing looks like some kind of Stanford University social experiment, give people something for free and tell them it will make them money, let them invite more people into network (the only way to get some PI is by joining trough someone's referral link, so it is in their interest to invite as much people they can) and collect private information from everyone.
PI should send their representatives here, these bitcointalk shills are making them look really really bad.
