The first post GOLD. This is exactly what's been happening in the last couple of years. Nevertheless, the scammers have been affected too (have you noticed some of they have just closed their "hiring departments" until further notice?). Well, it's like the Chinese taking over the world production; at first everybody complained about the "cheap junk," but over time they got used to it and started accepting it.
Another sign - check out the most popular research sites; a couple of them (including the foreign junk or ukessay) have now started promoting their "free content" to students. What they basically do is to dump all "customized papers" they have ever written as an effort to spam search engines in the hopes that some lost student would find the page and order from them. In the past, they would charge for such reference papers, but now nobody is buying all those pre-order essays so they offer them for free. Of course, they do it in a highly-unethical way because first they lie to their customers that whatever they order would belong to the customer only, but in the end it's not the case.
