Unfortunately, the sketchy link generator has been taken offline. I no longer have control over the IP address that the service previously used, and without it I don't personally feel that the sketchy links are particularly unique.
However, as this was a server that was of interst to some, I've provided a decoder before for any links that may have been previously generated.
If this is a feature that you're really interested in keeping, consider opening an issue and we can discuss possibilities.
