Paypal Chain letter to make money

I didn't quite understand the system. You have a paypal address. Then you send $1 to each of the six people or the six people have one common paypal address then you send $1 to that address or six people return $1 each to you or they collectively send you a total amount of $1 from a common address or they send $0.166666666666666666666 each from 6 separate paypal addresses or they thank you for your generosity or they mock you for your foolishness or they get richer by $1 each or $0.16666666666666 each or they express gratitude for your kindness or you feel cheated and being fooled by the ENTIRE chain system. I honestly could not understand it! And I feel a bit queer about chain system always. I say let's ignore the whole hoobahoobi and be happy.

As far as I'm aware, at least in North America, chain letters - both traditional paper ones and electronic ones - are illegal. Some are considered pyramid schemes, gambling, mail fraud or wire fraud. Others are just annoying spam. Like you, I would not get involved in any such thing.
