Resource packs server protection

people can get the texture from any minecraft server, please fix this

just go to .minecraft -> server-resource-packs take the file and rename it to .zip, and you will have the resourcepack of any server, is it allowed to send a youtube video showing this?

someone stole my texture, so I asked him how he did it, and he taught me it's very easy.
