As some others have stated, i tape for myself first but i do feel an obligation to also share what I recorded with the general public. I upload my recordings to the archive and i have a youtube channel for my videos.
As far as youtube goes, the only thing they're gonna do is slap a copyright on it so you wouldn't get paid for ads on the video, but the copyright holder, the band, would be the only people that could "strike" your video and get it pulled down. So if anyone has video, i'd encourage you to create a youtube channel, its a lot of fun and you also get your videos archived on the #1 video sharing platform on the internet.
