Is there really a bot smart enough to scan an article, then not only complain about the direct mention of IMAX (which is easy enough), but also be able to connect that mention of IMAX with a virtual reality system? I find that unlikely, unless the IMAX people had a specialized bot written just for them.
I'd certainly believe that an automated system found the article in the first place, but my instinct is that a human actually sent the letter.
