What's up with the local chatter on Aviation Emergency FREQ 121.500MHz AM in WV?

As long as I have had scanner radios, capable of RX'ing Aviation VHF AM, I have always had two FREQ's programmed, the chit-chat FREQ 123.450MHz, and the Emergency FREQ 121.500MHz. For decades, I wouldn't hear anything on 121.500MHz. Well, about 15 years ago, in WNY, I heard what sounded like a teen beat-boxing on there. (Some kid got Daddy's Aviation HT?) I've always heard chatter on 123.450MHz, some of that being pretty entertaining to listen to. However, this year, I am hearing all sorts of number exchange chatter on 121.500MHz. None of it sounding emergency-like to me. I would assume that these numbers are flight numbers, but why use a known Emergency FREQ to do so? This is SW West Virginia. Is anyone else hearing these?
