I received a text from this number with MY last name and a link to click.  The message text was "Hey (LastName)!  Your friend sent you a message on Cake.  https://goo.gl/N22Tvy"
It seems pretty suspicious.  I didn't try the link because I don't trust it. I read at another site that it takes you to the APP download page of Cake, which (if you install it) will then spam all of your contacts.
