Since known links to the video will be quickly blocked, share links using one of the many PrivateBin instances

https://privatebin.info/directory/

Or on pastebin sites

https://pastebin.com/6xeJuyeQ

Bookmark those links, and use them if you need them

TIP: If you use a PrivateBin instance which supports HTML (vim.cx is one I know off the top of my head), set it to Markdown format, and you can directly embed the video with HTML5 video tags. Great way to spin up a little one-off webpage with whatever information/media you want to add to it.

Example:

<video controls>
  <source src="https://files.catbox.moe/twpcwf.mp4">
</video>
