I don’t know the term for it (I’m sure someone who does will chime in later), but that still makes sense. It’s a way of typing things out how they’re pronounced. Some other examples includes: ‘at’ll (as a shortening of “that’ll”), ol’ (as a shortening of “old”, as in “good ol’ boy”), or the most common y’all being a popular southern way of shortening and contracting ‘you’ and ‘all’.
Note that I’m not claiming this is perfect proper English, but just saying that from the perspective of myself being a native speaker, it makes perfect sense to me, and just adds some character to how my mental voice reads their text.
While I agree that I think that in most formal situations you should not write that way, I personally see no problem with a more casual writing style like that in a post like this. Seeing as it’s written as the writer’s personal account of their journey to regain privacy, a slightly more casual writing style is fitting. The benefit of a more expressive writing style, in this context, outweighs the potential reduction in clarity, given that most readers will be able to use context clues just fine.
As a side note, y’all shouldn’t be so quick to downvote this guy. While I don’t agree with his perspective myself, it’s still a fair point of view to have, and it ain’t like it’s being written in bad faith or such. But that’s just my two cents, I s’pose.
