We analyzed data.pnj.com and found a site that is almost completely opaque. There is no about page, no contact information, and no social media presence. The domain's ownership is hidden in a way that even the public WHOIS database shows no record of it. For most legitimate websites, you can at least find a name or a way to get in touch. Here, there is nothing.
Is data.pnj.com a scam? We can't say for certain, but the lack of transparency is a major red flag. Without knowing who runs the site, you have no recourse if something goes wrong. There are also no user reviews or web archive history to check. If you are considering sharing any personal or financial information, you should first ask: why would a real business hide so much?
Our review of data.pnj.com found no clear indication of what the site actually does. The homepage text was unreadable, and the only content we could retrieve was from an archived snapshot months ago. For any site that asks for your trust, this level of secrecy is unacceptable. When in doubt, don't engage until the people behind it step into the light.
