5 minute crafts and thier many channels are the modern version of "number stations"

for those who don't know what the number station is this half as interesting video will explain. https://youtu.be/ZQpDoR8ZGTc

the youtube channels which includes 5 minute crafts have some strange cryptic comments which are mirrored on the sister channels. they are Russian in origin and I think they are a modern replacement for the number station.

people seem to think it's ai comments, but I don't think so.
