It is a joke as Coinmarket did before on april fools day also. It means that they support them. IT looks like there is a fight in the market and some strong hands or whales are trying to attack each other. But WSB changed many things in the market and it looks like change started.
indeed its only a joke,
so for the OP don't take it seriously, and i suggest the OP to click the link about WSB on coinmarketcap and i believe he will know what Wallstreetbets is
