Assuming you follow all the intended instructions... and keep / maintain a list of email addresses (which hypothetically could be sold to an email service as people will maintain their paypal accounts to keep "getting paid") then there is indeed a service being provided...
As for a reproducible source of income that just floods your paypal account with thousands of dollars every time you do it...
I'm not seeing it...
lesee....
assuming you were willing to sign up in the first place...
what are the odds ya will pony up the $1 each and every time ya get spammed by something like that ? ? ?
BTW, if you are serious about attempting such a thing.... send me all $6... and I'll send ya back $12 as soon as I sucker 4 more people into sending me $6....
Cheers
