Cory Monteith's final tweet about Sharknado deleted by Twitter

Twitter has been deleting very important tweets today. First it was Ellen DeGeneres' epic selfie at the Oscars.

Now Cory Monteith's final tweet before he died, which was about Sharknado on SyFy is gone!

Is it a bug? Is it permanent? What is happening? And just went Glee club was finally shut down by Sue Sylvester on Glee. Is this on purpose?

This is simply a lesson that we do not control what we post on these massive Web sites. We are the product.

Update: It's back! Sharknado is back! And so is Ellen's Selfie!
