I’m very sorry to confirm that this is a known scam site from the past which appears to be back. We have reported it to the registrar and their host multiple times, as have others in the community. We cannot force their host to take down the scam.
If you file a report with your local authorities, and the authorities send them notice, their registrar and host may take action.
Can I ask where you got the “btgonline.info” link? I’m assuming they must be advertising it or posting it somewhere, and I’d like to be able to warn whoever is spreading the scam. (Advertising website, journal, etc.)
