Le site demonoid.pw est-il sûr ?

Coming back to what it was, it is the actual site, not a copy. There is much suspicious, though. In particular, "Your Internet Provider is tracking your torrent activity!" is simply a false claim to sell malware VPN software. Look up how copyright complaints work. It's not your ISP. Your ISP simply responds to a complaint by a copyright owner about an IP address. They don't tell them who you are, and don't do anything until you have multiple complaints against your account. At any rate, the statement is false to try and get financial consideration, which is the definition of fraud.
