1. If you post an excerpt but not a link, you should be banned for a year.
2. If you link a video without a source or link for further context, also banned for a year.
3. If you link something and ask anything like "okay, which one of you did this?" or "what is going on here" or "where is this" or ask for more information from others without saying where you got the video or pic posted, you get a lifetime ban. We don't know, you're the one who posted it. Therefore: done, forever.
