I realize you are the admin here and at the risk of upsetting you I have to tell you it is not illegal to get a copy from someone
Maybe artists need to know this as to make a more informed decision about offering FREE STUFF.
When a copyright owner of a product places the item in a public setting with the intent that it be allowed for download and/or use by the general public free of charge It loses some of its protection under copyright law.
But asking someone who has it for a copy does not violate any copyright .
If the owner decides it is no longer available to the public a notice must replace any/all notices where it was listed.
Then it would be illegal for me to ask for a copy.
(I have worked in law for better than 20 years. if you are doubtful of this information I encourage you to seek a second opinion.)
