How to hide files from companies who take down files quickly

Whether a company will find out and take it down is up to them. Some ways to combat that is to obfuscation of the link by using a hide redirect/hide referrer and not labeling the file uploaded with anything that can use to identify it. People will know what the link is by seeing it here and after opening file. It's how a link to the Disney TVA leaks are still up on archive when 90% have been taken down because they are uploaded as jumbled names of the video files but if you open and watch file you will know which is which.

Use a random name of the file when uploading to archive or file host and obfuscate/hide the link with a redirector so they don't know where the link is coming from.
