That's good they have options to verify the mirror links. So users would make sure they on the right website.
People must at least know one of BC.Game links that can be either the main link or a mirror link, then they will be able to use this verifier for checking any link as whether official mirror link or a phishing link.
People must start somewhere and hopefully it is an official link. To reduce risk of falling to phishing sites, they must search with different search engines, ask AIs for example and check all given results whether it matches with each other. If they find an official main link, they will be all good after that with this verifier.
