Uh, what? I just tried it a few times, and it seems to just follow the redirect each time, always ending up back at the original target URL I entered. How many times did you have to "repeat" to make that happen?

No, that's not what BubbleRings said. BubbleRings said one site on VirusTotal reported it was malware. That sounds like a false positive because the URL is fishy, which is the entire point of the joke here.
