Ah, I know the lot. I investigated them some time ago and couldn't find the original source. There are often clues within edited posts (i.e. why did they edit it) and there were very few posts that had been edited (which is suspicious in itself). What I did notice is that one of the edits was correcting some grammar - so somebody who (I believe to be) fluent in English had read it after it had been published.
The other edits often removed a quotation mark (") as the first and last character of the post. So whatever tool had been used to translate or create the post wraps it in quotes.
Looks like I looked into them on 12th April last year - 12 accounts at the time.
I have no doubt though that it's not authentic content and believe that this account holds the key -

The content was genuine at the start, written by a guy from Pakistan and then it changed completely - like it was being run by somebody completely different.
