My reading of the tweets was that whomever was flagging the "typos" wasn't flagging actual typos, rather, that they were flagging words intentionally spelled the way they were to convey some regional dialect. Sometimes, things are spelled in a certain manner that is non-standard to convey an accent or mannerism of a character in a fictional work.

It would have been nice if the tweet poster would have made this abundantly clear, but alas. But a "typo" to me implies a mistake, and it's not clear to me if the flagger is flagging mistakes, or something that was intentional for the purposes of storytelling.
