Coinmrket i think is just a regular site and May be it was paid by that company to advertise or promote its own site. Seeing it is acquiring many views, its good opportunity to advertise site links. Because I have seen many sites in coinmarket cap and annoying as they be, that is how a site is earning.
As someone who has a few years in the media as a journalist, I have come to realize that most media houses survive and are able to take care if running costs through patronage (money from advertisers who could be moneybags or unscrupulous politicians) I know and understand that. But there's always some reputable media houses that stay away from that. That is what CMC should be doing. It should stay away and not let go of its reputation because of some cash in the offing. It shouldn't be allowing fraudulent schemes advertise on its site. Doing that will make it lose face.
