Now THAT is a stinker straight out of 2015! I guess some things never change, not with the potholes and skanks on my street and not on bitcointalk. As long as there's a service that pays non-English-speaking people to post in English, we're going to end up with turds like that.
You know, as someone who speaks a few languages, sometimes I read an article, post or comment and I have a pretty strong idea of the person's native language. I just had this idea: a program that similarly to how translators guess the language of the text you put in, tries to guess from what language a text has been translated into English. It should be especially easy for anything that comes straight out of Google-translate.
A trivial implementation could just try a bunch of common languages and check if what comes back out seems like somewhat good writing.
