Sadly Vimm last time I check does not allow videos to be saved. So once the live stream is over they are done. I don't really know that site he is uploading videos to.
If it was YouTube or Dtube (and not getting upvotes from them) then he fit right into my community if he is talking/banter/uses his username and bring up platform(s) he is using in the video.
Video content can be a bit tricky a lot of it is sadly lacking detail needed to determine if the person who uploaded it is the owner.
