That doesn't make InternAnon's claims any more valid. While "Polé" is pretty close to "Polly," the anon could have easily just made a lucky guess, or their made-up name for the character might've stemmed from pic related.
Several other announcements we got today also prove that the "intern" was a fake. Anon didn't state that Sasha was the name of one of Anne's friends (instead calling them Amy Lee and Charlene), Brenda Song--the show's biggest selling point--was never mentioned as part of the voice cast, and some other VAs were revealed today, with Eric Bauza not included.
It was all a ruse.
