What you mean videos on Nostr directly? 👀

Uploading videos to a web server like Nostr.Build & then linking directly to the video file. I actually prefer when people post links to songs on YouTube. It allows me to play then on newpipe while continuing to browse on Nostr.

The YouTube algorithm is clearly trying to spin people up towards nihilism.

Does it clog up relays with data? Is it feasible?

Videos aren't stored on relays. They are stored on #Blossom or similar.
