If you want to stop reposts that are illegal then I recommend going to https://stopmodreposts.org and doing the following things
1. Get the browser extension
2. Put a warning on your mod, resource pack, modpack, or any other project you post saying any other post is illegal and might be malware.
3. Optionally you can tell google or make a DMCA takedown request to remove any illegal reposts.
