I got it in my email tonight. Strongly suspecting it to be spam (at the very least) I asked Uncle Google "WTF?"
Various places report it as spam, some say it's phishing, but the general consensus seems to be that no-one has actually added anyone - the company is just bombarding teh interwebs. Seems like there is possibly an actual app although, given the way it's being "promoted", I shudder to think what it might be raking off your phone if you install it.
Given the company's obviously a pack of dirty spammers, I'm hoping ISP's here will block the domain.
EDIT: Purdue University is saying it's a phishing email and clicking it's links will take you to a malware site.
