https://expresscrypto.io/ have stolen faucethub's base code including the chat and rain system and deny all claims of it. They literally stole the whole website and are making money off of people with a shameless ripoff!
Such irony that you've mentioning they copied the whole website yet it seems that you apparently didn't have any valid proof at all of its 'similarities'. I've looked it up and it was pretty much different. Also, codes are often the same dude. Have you even know anything about chat systems and how to program them? Do you even have any valid evidences that they clearly copied everything? Is FH chat even an open sourced code? It's clearly not as mdshare said that the dev were the same. Therefore, we cannot justify anything as a scam, not unless there are confirmations with the team having no legal documents with their operations.
