Xyz used to be the cheapest domain it's mainly used by Ponzi and MLM operators a wallet will not and should not use this domain name
But some greedy man who are looking for a bucks for free don't care what the domain name is used to making the giveaways. xyz domain is not only very cheap but also some domain provider give them as free.
btw the site maybe down already, I can not access it anymore. Some bad dishonest people are taking the advantage of boosting feature in Facebook to promote there scam trap. in this modern world if people don't care to keep secure in internet then we can not do anything tbh.
If I'm not mistaken the price of the xyz domain is $ 1 I used to buy it for a site to create crypto article content, but that's how greedy they continue to be blind with many domains that are used every time they change the site with a new domain, maybe it's not how much capital but they definitely have more stock if their phishing site is found out it will be changed again and this is what they always do.
They promote with a sponsored page, is it paid with Facebook?
I see now a lot of scammers who do this to trick them with their tricks.
