I can’t take you seriously when you are anon. If your information was legit, wouldn’t you want the credit? Anyway, I don’t recall her changing her tumblr and there is nothing on her youtube nor twitter that states otherwise.

If there is anyone that wants to back up this anon’s opinion with actual proof, then so be it. But until then, I’m pretty positive this is her only tumblr (as stated on her twitter) http://arianasings.tumblr.com/.
