Finding someone online who has mentioned having lost media (and maybe the only known person that has been mentioned to have it) and being unable to contact them for any of the following reasons:
1. They have social media but don't allow or have disable comments, private messages etc... 2. You can contact them but they don't respond on the one (or several) known means of contacting them 3. The person(s) account(s) have been inactive for a long time with no way of contacting them that will be likely to get a response and no way of knowing if they will use those accounts again 4. They have the media but refuse to post it for whatever reason, like its copyrighted and they don't want to potentially get in trouble for leaking the media.
I had this exact issue when trying to locate any episodes of "The Adventures of Grady Greenspace" I read a comment from a person who said they had some on VHS but didn't have a way of copying them off the VHS. The comment was around 8 years old when I found it years ago and there was no way of contacting that person that would get a response so I am still trying to find any episodes of it.
