The scuttlebutt is that buffalo as a verb was only attested very briefly in upstate New York and the Midwest for a brief period of time in the early 1900s. It never spread nationally, and definitely not internationally.

However, checking Google ngrams shows that “he buffaloed” and “was buffaloed”, (to ensure it’s being used idiomatically as a verb and not just in the famous example sentence) emerged in 1900, peaked in the 1950s, but has sustained small but constant use in published print since then. I was actually expecting the ngram to rapidly drop off and never recover… shocked to see that some people still use it as a real phrase.

Not that I’ve heard of. Now, whether Homo sapiens idaltu is a real separate species from Homo sapiens sapiens is disputed, so there’s a question as to whether the second sapiens actually differentiates us from anything… but I haven’t seen any signs of any consensus against calling ourselves Homo sapiens sapiens to date.

So, once upon a time, the radio airwaves were free for anyone and everyone to use as they liked. There were incompatible protocols, congestion, crowding, and so on and so forth. One day, the Titanic sunk, and a major contributor of it was the fact that there were no standards for ships to be listening for distress signals on the radio.

So international regulations were established be treaty, the Radio Act if 1912 in The US, and the International Radiotelegraph Convention of 1912. These laws and treaties not only established mandatory radio watch for ships at sea, but also sought to reduce crosstalk and bandwidth hogging by people— you’d need to get a radio license to transmit on a specific frequency for a region.

A public spectrum was established for anyone to use, and another spectrum was reserved for dedicated amateurs to advance radio technology (requiring a test to prove dedication— HAM radio), another spectrum was dedicated for government use (such as police), another for hospitals, and another segment for commercial usage.

If you violate the licensing requirements, you are a pirate radio station… and this is actually taken quite seriously. Regulators will actually take measures to track you down. One thing that the HAM radio community does is something called a “fox hunt”… it’s basically like a region-wide game of hide and seek, where the hider is repeatedly broadcasting a radio signal, and the seekers use whatever technology they can muster to track the hider down. The hiders also use sophisticated means to hide their location, such as bouncing signals off of water towers to hide the origin and other even sneakier tactics. Fox hunts are a lot of fun, but always end up with the fox getting caught.

Pirate radio tends to end up the same way.
