Please do not post a bypass, privacy leak or denial-of-service technique in a public issue while it is still useful to attackers.
Open a private GitHub security advisory for CreeperHost/PacketWard with the affected Minecraft branch, loader, PacketWard version and enough detail to reproduce the problem. Logs are useful, but remove player addresses, lookup prefixes and other identifying data before attaching them.
Ordinary crashes and compatibility problems can use the public issue tracker.
