It's kind of one of those things that means people have to start in the shallow end of the pool and wade around a bit before they go swimming in the deep end and get their floaters removed after they learn to swim.

I don't know what would cause one to receive their handshake again aside from a system glitch. Haven't seen that before. I think I had my handshake for about 2 weeks or so before it was removed. They want to make sure people aren't just "drive-by" shills, etc.
