If I can express my idea, I say that:
I understand what you say about netiquette, but when you publish a resource on the network, whatever it is, it becomes public. It is therefore useless to get angry or be surprised if the link is published in other forums, it is normal.
If one does not accept these conditions it is better not to publish at all.
I say this from personal experience, I am Super MOD on another forum (I do not say the name but many know me) and I have seen things of all the colors. My links have been published all around the world, even in China I found them, but NEVER it occurred to me to delete them.
This is my idea of netiquette, obviously different from yours
