Funny is how much is this SF for you. In country where I live these people are called "słup". Literally "pole". In english it would be something related to "bogus company". People who for money, drugs or alcohol do stuff for you. Like buy and register sim card. Provide you their identity details with ID. For 200 USD they can even go to the bank and create account providing all details to you. You even can register fake companies on these people if you get them flat, clean clothes and something to drink every week :) It is so many scams in central and east Europe, that for me funny and SF is that if you do not understand something or you didn't see it, it's a fake in your opinion.
