While 3,000 words a day is easily doable if your day is a wide-open schedule of nothing like Ruby's is, she still didn't do it and just lied about it instead.
Ruby clearly states she wrote 2700 works in a single day. We'll see...
The vlog starts at what the clock says is 7:20am (it gets a lot darker than that by 7pm, even after daylight savings, so it's definitely supposed to be morning).
Ruby checks the word count and she has 1,950 words after just a couple of seconds of timelapsed typing.
The clock is shown again and she's apparently written 1,950 words in (at most) 45 minutes. Preposterous bullshit.
And then she's suddenly finished, with the weather and time of day outside exactly the same.
She blatantly just filmed a couple of minutes of her cutting and pasting crap she already had to hand in and out of a document to film the numbers jumping up to look incredibly productive without any thought as to how easy it'd be to see through her bullshit.
