While I wouldn't be surprised that scammers try to exploit this situation, that's not the case here. As explained by CMC, that's just a joke and will be removed eventually. Afaik they did similar things in the past.
I think it is a dangerous joke. I saw this today too, and I was a bit confused. I was thinking if someone already created a token called wallstreetsbets, and why would CMC be promoting it.
AFAIK they haven't created one... but someone could, and just try to sell to someone for 480 USD, which is a lot of money.
