YSK long noise videos cant effectively be compressed and as such take quite a lot of storage space and bandwidth. So if you want to keep the hosting costs of social media platforms low, for example when going public, you definetly wouldnt want disenfranchised users to upload them to your platform. This is the kind of noise you would want to avoid: https://stackoverflow.com/questions/15792105/simulating-tv-noise#15795112
Oh sorry on Jerboa it does not show Community descriptions and I did not see the rules. But I am kind of curious tho, does it need do be worded like that? I wrote you should know this, if you want to keep the costs down, doesn’t that count? :P
