A Google+ loophole used for a creative campaign

Nitpick: I'd be even more impressed if they ran their campaign through a spell checker.

An invitation probably isn't enough. I've already got two and still cannot sign up.

I don't know if this tweet is true, since I'm already on G+. The rest of you can try and report back:<p><a href="http://twitter.com/#!/rothgar/statuses/87767198084505600" rel="nofollow">http://twitter.com/#!/rothgar/statuses/87767198084505600</a>

So they exposed all of their contacts on Google+? I wonder how the contacts felt.

I don't think its a loophole, It must be intentional.<p>Second way which is popular now, you can add the gmail ids in your circle and share a comment to the circle. This will send a invite to everyone in the circle :)

You don't need the invitation via email to get into Google+, just tell your friend to invite you (tagging or posting, whatever). Go to <a href="http://plus.google.com" rel="nofollow">http://plus.google.com</a>. Log out of your Google Account. Log in back. Voila!<p>More information: <a href="https://plus.google.com/107083942933833320656/posts/2fLmrDmyAKL" rel="nofollow">https://plus.google.com/107083942933833320656/posts/2fLmrDmy...</a><p>Still working, up until now...

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.

Have they since closed that loophole? I can't see a way to use it.

Well you COULD just share a link to the people wo want to join: <a href="https://plus.google.com/up/start/" rel="nofollow">https://plus.google.com/up/start/</a>

(How is TNW getting all these Circle stories?)
