cherrys I don't recall anyone saying it's unsafe. All @Varrience said was that it was a very naughty hacking website, which it is. Basically, when you go to the link (which is totally safe, don't worry), it has a text box asking you for a project's ID. Once you input it and press enter, it will bring you to a large set of tables containing the project's keyValues. There are some buttons that you can play around with to essentially do anything to the keyValues, including changing them, deleting them, creating new ones. The single most potent feature of it is the "Clear All" button, which does just that: clears it all away... have fun!
