The whole point of a job is to earn money.
If you are paying money to work then that is not a job.
So don't waste your time on these things.
Also why would anyone want to work for crackers like $3-$5 per job? Especially in first-world countries where that amount will not buy you anything, and will easily be swallowed up in service fees? For 3rd world countries I can at least understand why they would take up such a thing.
You will be surprised to see people are paying money in order to get accepted to work in third world countries, it's already open secret. If it's ended scam, the spender will not report the receiver because "bribing" is actually broke the regulation, so they can only trust and hope they will not get scammed.
With such mindset, that might be the reason why they don't mind to send money in order to get money, which make this game quite famous and get many victims.
