Here’s a thought: Run a WHOIS on the domain you are thinking of investing in. If there is NO contact information, or the registration is PRIVATE, that should be a red flag.
Think about [Merlinlab.com](https://Merlinlab.com). Run a WHOIS on them using this site: [https://lookup.icann.org/lookup](https://lookup.icann.org/lookup)
See how their registration is private, and their site was registered by a company, [DomainsByProxy.com](https://DomainsByProxy.com), whose job it is to make sure you cannot ever know who is running that domain.
Now, do you STILL want to put your money into that site? Think about it.
