There are quite a few errors in the presentation that seem intended to annoy detail-oriented people. One that stood out to me was the use of backslashes in his website URL.

In the paper, at citation [2] where he talks about mal-formatted URLs and fixing punctuation on Wikipedia, the footnote citation is a broken (and line-broken) link to the Wikipedia page.

Also, there is a [1] in the footnotes but not in the main body.

The pdf had absolutely horrible keming (long words were visibly broken into their component parts) on my mobile reader which I thought was a deliberate part of the joke until I opened it on desktop and it looked fine. I assume it was perhaps substituting a different font or something.

And the apostrophe is a single left quote.

Yeah, some of those (like the backslashes) were clearly intentional. It didn't look to me like the "Is this" / "This is" was, but I guess anything can be put down to being part of the joke.
