About ExploitPreventer

ExploitPreventer is a client-side Fabric mod for Minecraft: Java Edition. It prevents translation key and keybind resolution on sign and anvil screens, blocks resource pack URLs that point to local IPs, and uses a separate resource pack cache directory for each account.

It does not block mod detection via plugin channels, and the project states that use is at the user's own risk regarding bans or other consequences.
