The only case were Pi is lost is if someone created 5 fake accounts to fill up their security circle, and then those accounts are found to be fake. Two things can happen in this case: If the person created those accounts themselves then all of their accounts are lost, including the main one (one account per person rule). If that person did not create those accounts and somehow got tricked into adding them to their security circle then only the bonus is lost. There is one case where the person can save their main account: If they self-declare the fake accounts as fake. We understand that people sometime may not have known the rules in advance or they simply make a mistake which they regret and want to correct. In this case, they only lose the bonus.
Another principle is to not leave any real pioneers behind. So we are still aiming to create a KYC method that will allow everyone to participate.And give people many chances.I am sure some people will just not do it. And this affects everyone proportionally.you need only 5 people in the security circle. But it's ok to have more.
if you accidentally have the wrong person in, you can change the right person later once you figure it out.If you have 3 people in your security circle and the same 3 in your earning team, and one of them is fake, then bonus from the fake will be lost.if you have 5 people in your security circle and one of them fake, but you have 6 people in your earning team and 1 is fake. That means that you could have had 5 real people in your security circle. So we should probably take a note of that case.
