Is is a Babypips phenomenon, Viper.
The irony is that most of the posts you’re referring to actually started out in reasonable English, in the other forums in which they originally appeared, before being pasted in and out of another language or two and then back into a kind of English with free online translation software to change their vocabulary, so that they’re no longer too recognisable.
That’s what people from forum posting services do.
Otherwise they’d have to know something about the subject, to make the posts they have to make.
That’s VERY much a Babypips phenomenon.
But I suppose without them, there’d be so little participation here that Google wouldn’t even crawl and update the site’s indexing and there’d be almost no traffic at all, and very little income. So it’s kind of understandable, given everything that’s happened here, that things like this are tried. Most of the people who complained about it have already left, after all. The decline is now self-fulfilling.
