Another tactics I noticed scammers use is to create mixer review websites with real reviews and rating, but they are using fake links for mixers.
I didn't know that scammers were so determined to get our money through tactics like these that seem quite sophisticated, scammers are everywhere, once they see profit in a certain niche.
Fake links are very common spread way sed by scammers. They use it literally everywhere. There is a site in Ukraine, called OLX, where people can sell their staff they don't need anymore. And there are lots of frauds there by providing fake links, following which means you will lose your money. And it is a second hand site we are talking about. I can imagine the scam scale when it comes to bitcoin mixers.
Wow, amazing to learn that OLX is also available in Ukraine, this once was a very popular e-commerce platform here in Nigeria where (like you said) people sell their old stuff, things that are perhaps still working but they don't need it anymore, stuffs like cars, laptop Computers desktops, bags, shoes, just about anything at all..
But this site is no longer in existence over here because the fraud on the site became really too much and overwhelming, they had alot of users and seeing that this users were beginning to leave the site due to the massive scam happening there, another company known as jiji came and bought it over and rebranded it..
So indeed, as long as the internet is working, there are massive online scam every where, it's not something that is peculiar to mixers alone, scam is everywhere and internet users are advised to always be very careful.
