This was how I got invited (out of the blue invite advertising some site) and how I invited over 20 people over a 24 hour period (tagging them in a photo/status update or sharing a status update to a circle/email address). They didn't get any "Exceeded Capacity" messages although the real invite UI still doesn't work. And it was after I heard on HN/Twitter that "the loophole has been closed". Maybe some cliques are more welcome than others.
