Movement checks ship alert-only on purpose. That's where false positives come from. Clear flight is still kicked through blatant escalation.

Details

Reach reach

Flags hits landed from farther away than the game allows. Two over-reach hits are needed before one flag counts, and ping is given slack.

Hit angle angle

Flags hits on a target that sits far outside where the player is looking. Only very wide, off-centre hits count.

Hitbox hitbox

Flags hits whose line of aim misses the target's body. Aim is sensitive to lag, so it alerts by default.

Multi-aura multiattack

Flags attacks on several different targets within one tick. Crowded fights are tolerated.

Auto-clicker cps

Flags click rates that no hand keeps up. The limit is set to catch clear auto-clickers only.

Click pattern clickpattern

Catches auto-clickers tuned under the CPS limit. People click with tens of milliseconds of jitter; software is metronomic.

Aim snap aimsnap

Catches killaura snapping onto a target in a single tick and landing dead centre. Both halves must happen together.

Hit through walls wallhit

Flags hits with no line of sight to the victim. Fences and corners are allowed a clipped hit or two.

Attack while using useitemattack

Flags attacking while eating, drinking or blocking, which the game doesn't allow.

Auto-totem autototem

Flags a totem appearing in the off-hand faster than a person can react after one pops. Holding a totem early is never flagged.

Speed speed

Flags moving faster than sprint-jumping allows. Speed potions raise the limit. Moving at 2.2× the limit for three ticks is kicked.

Vertical vertical

Flags rising faster than a jump. Jump Boost, wind charges, slime, riptide, elytra and levitation are all accounted for.

Fly / hover hover

Flags staying in the air with almost no vertical movement for seven seconds or more.

No-fall nofall

Flags long falls that take no damage. Mace smashes, water, hay, slime, honey, cobwebs and powder snow are exempt.

Water walk jesus

Flags walking on top of water or lava like it's solid ground.

Timer timer

Flags a client speeding up its game clock. Readings are thrown away whenever the server lags or the client is catching up.

Nuker nuker

Flags breaking blocks faster than tools and enchantments allow.

Fast place fastplace

Flags placing blocks faster than the game's placement cooldown.

Block reach blockreach

Flags breaking or placing blocks from too far away.

Freecam freecam

Flags mining and building spread around the player while their body stays still, the pattern of a detached camera.
