I think he's commenting on the type of domains people have registered and are trying to resell at dynadot, and less about dynadot. I'm not sure what kind of morons would reg domains like that other than phishing/scam artists. I get canadapost related phishing scams by text message on a nearly daily basis.
Although I suppose its also a kind of negative commentary on Dynadot if scam artists have specifically chosen to use Dynadot for some reason.
