This was posted to slashdot after the "go live" time of the app/website, but only links to articles posted prior to the launch that speculated it was a hoax.
One of the authors (Alfred Ng) of one of those articles wrote a follow up piece *after* the launch, with the actual details of what the hoax actually was (A marketing stunt) and what registered users saw when they used the app at launch...
When the website went live at 5 p.m. on Monday, the app asked users to sign in using their Tinder, LinkedIn or create a new account. It matched all users up with a fighter named Dudecati. The user wouldn't be able to do anything but type back at the automated response. At the end of it, the bot tells users:
"ok in all seriousness though you're wasting your time here," and then redirects you to the group's website.
Why won't sharks eat lawyers? Professional courtesy.
