Question about marketing a property online with no license

[Mon Kaaaaaa]

A person I know of has been very successful listing commercial properties online over the past year in order to locate buyers. So successful that this person sold a few 5 million+ properties. This person has no licensing and has nothing to do with communicating with the prospective buyers or filling out paper work. They merely place ads in the owners name with the owners permission and receive a commission. All of the paper work has been done through the buyers broker and real estate lawyers. Is this something that is allowed in the US? Seems like it should be but I am just curious because this person seems to be doing very well.
