Obfuscating filenames of the uploaded archive is not effective, nor is password protecting the archive. Can somebody suggest a method that has worked for them? Perhaps a link protector service, perhaps requiring people to download a password protected archive that contains a text file with the link inside, perhaps encoding the link in a fornmat that bots cannot read (eg Base64).
Thankyou for any wisdom people can provide. I’m sure it will be of use to others wishing to share.
