If this doesn't make sense to you right off the bat, let's sprinkle a little context on this to see if that helps.
Over the weekend, Piers Morgan basically got his arse handed to him by JK Rowling after she pointed out what a gigantic bell-end he was on Real Time With Bill Maher. Morgan tried to fight back, of course, claiming that he'd never read a single book written by JK Rowling - as if that's some sort of response.
However, in the midst of all the toing and froing, the Twitter account of a bookshop in North London decided to step in and correct that mistake - whether Piers Morgan liked it or not.
The Big Green Bookshop's Twitter account is sending each and every word, sentence and punctuation mark to Piers Morgan's account. The man behind the account, Simon Key, told Sky News that he's "doing it because Piers clearly spends all day on Twitter staring at his timeline. He clearly needs a bit of a break from all the abuse, so as he mentioned that he hasn't read any JK Rowling, rather then having to tear himself away from Twitter to read it, I'd tweet him."

As of writing, Simon is on Page 10 of Harry Potter & The Philosopher's Stone. Again, this is really happening and you can follow the whole thing on @BigGreenBooks.
No word yet if Piers Morgan has blocked the account or if he's actually getting into it.
