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.
The only legality still attached to the product is the creators terms of USE. IE personal or commercial not re-selling or placing up for download on thir site etc.
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.)
