Rules here are sensible and even generous.
You don't need to use common sense when interpreting these rules, but we might.
Staff make the final decision if something's not clear.
crack into a game server and add fake games or bones.
exploit vulnerabilities in a weak random number generator.
exploit memory corrupting bugs.
use disconnection at critical spots to hide a death from logs.
willfullingly disrupt the tournament experience for other players.
Feel free to:
All games escaped or quit within the first 10 turns or have more
than 10 turns but have finished within 10 seconds are hidden on the
look at player
of previous or current games.
use NetHack playing bots or so called "augmentation" tools
exploit well known game bugs (eg, Astral call bug, floating
wand wresting trick, gold duplication bug, artifact naming trick,
etc). Some of these may be fixed on some servers.
make multiple accounts.
in general, anything the game says you can do.
