Is Unblocked Websites safe?

Unblocked Websites routes 100% of browser traffic through a hardcoded datacenter proxy, not just games or unblock sites.

Clicking the popup's Unblock button installs a PAC script that returns the same proxy for every URL visited, even though the code also contains an unused, commented-out version that would have scoped it to a handful of specific domains. The proxy IP is picked from four hardcoded datacenter addresses and authenticated automatically with a single hardcoded username and password baked into the extension, so the user never sees or controls which server their traffic goes through.
