It's safe to look at this site, but I strongly suspect that it is a phishing site trying to fool people into delivering account numbers. Why is this site still active? Why isn't there a way to flag these abusive practices?
Sure, I sent an email to Chase's "report abuse" address, but I doubt I'm the first to check out the web site. There's the Phish Report Network, but that appears to be designed exclusively for e-commerce companies to use.
What users need is a dynamic, community-defined extension to flag phish sites. Then, if you visit a site that other users deem suspect, you would get a visual warning. There's this extension from Netcraft, which I'm going to try now. At least it seems to have a feature that lets you report phishing sites.
