SimpleAntiFly

SimpleAntiFly — Lightweight fly hack detection & punishment for Spigot, Paper, Bukkit & Purpur (1.21.x)
SimpleAntiFly watches for the tell-tale sustained rising or hovering movement of a fly hack client and takes action automatically — without punishing your legitimate players.

✅ Smart detection, zero false positives from:
Elytra gliding (+ landing grace period)
Wind charge / TNT / piston knockback launches
Ender pearls & chorus fruit
/fly, Creative mode, Spectator mode
Vehicles, water, lava, ladders, vines, scaffolding
Levitation, Slow Falling, Riptide tridents

⚙️ Fully configurable punishments
Set up escalating stages in punishments.yml — warn, kick, ban, or run any console command you want (works with LiteBans, AdvancedBan, or vanilla commands). Violations auto-reset after inactivity so players aren't punished for old flags.

🛠️ Simple to manage
/simpleantifly reload — reload configs without restarting
/simpleantifly violations — check a player's flag count
/simpleantifly clear — wipe a player's violations
Permission-based bypass for staff & trusted flight plugins
Live staff alerts when a player is flagged
