Common but it's one of those things that should come with a label on every single ticker or such. As it stands, without any plan or goal to become profitable, investors should acknowlege that they are incurring extreme risk and are investing on concepts outside of any actual plan to eventually turn a profit. To top it all off, they are just crawling Google. Google could potentially shut their entire game down any day. In a different era's market I would expect the SEC to shut it down and ask 'Why are you IPOing?' and 'Is this an attempt to exit from a failing business by misleading investors?'.
