We get a lot of questions about sites that offer little to go on, and blockmsg.greennet.net.vn is one of those. It's online, it loads, and it passes Google's safety checks. But that's where the good news ends.
This site doesn't tell you who runs it. There's no contact page, no about page, and no social media presence to confirm they're a real business. Most legitimate services make it easy to find a phone number, email, or at least a physical address. Here, that information is missing entirely.
For a site that deals with messaging or any kind of user data, the lack of a privacy policy or terms of service is a real gap. Even hobby projects hosted from a .vn domain can be legitimate, but the combination of total anonymity and zero legal disclosures means there's no accountability if something goes wrong.
If you're wondering whether blockmsg.greennet.net.vn is a scam or just an unfinished project, the honest answer is that we don't have enough information to tell. The safest move is to assume it's not worth the risk until the operator proves otherwise.
