I would guess HBO registered SeeFood Technologies Inc. as it definitely looks like an official stunt otherwise it might have been taken down by now. It's not uncommon for them to do this - see http://www.piedpiper.com/ and http://raviga.com/
How would you know one isn't a student anymore? I'm pretty sure students don't lose access to their .edu email after they graduate (with most schools, at least). Not that I would do that, but there are people who certainly would.
