there are many scammers.
I can tell you dozens of such cases. I don't even know what to share with you.
I have been making money on the darknet for a very long time and have gained a lot of experience. Of course, I lost a lot of money and got into difficult situations.
There are many fake services on the dark web, but most of them are owned by just a few people. they control most of the dark market.
I can only say one thing, if you want to find real services, look for sites with advertising. Among them there is a chance to meet the real ones.
And you certainly can't trust someone who doesn't have a website. Also, one-day sites cannot be trusted. These sellers are definitely scammers.
