If these sites just go for some verification before promoting these scams, it would be very good for the visitors.
This is the reality, because people know how much money in the cryptocurrency ofcourse a lot of people will do shady things to have a part of it.
The sad truth is in advertising industry as long as they are paid enough to advertise a project they will advertise it event it turns out into a scam.
What is happening is that, most of the time, advertisers are the bounty hunters as well. I became a bounty hunter before, and I strictly not supporting scam projects and I will never knowingly support bounty projects. Most of the time what is happening is that they promise good amount, not that high, but just in exact, so you will believe the project because the particular scam are those that promise something that is too good to be true. In this case, you knowing the project is legit will turn out to be scam.
The lesson here, you cannot determine now, what is legit and good unless you haven't really tried and proved it. So we really need to take risk in order to earn profit while not supporting these frauds.
Bounty hunters were not to compare to Web advertisements.
There is a little bit of difference withing a bounty hunter and an advertisement posted on a website. Let's make it quick
Bounty Hunter - being a bounty hunter will not give you any payment until the end of the project, whether it is legit or not, your payment will be on hold and cannot be touch. It means bounty hunters are working for the promise bounty payment.
Web advertisement - It is being paid at the same time as being posted the ads on their website. Whether the project is a scam or not, they are already paid.
Both cannot determine if the project is legit or scam; However, bounty hunters will remain as one of the victims of those projects.
