Nineteen checks
Each one switches on, off and tunes on its own, and each carries what it detects and what confuses it written next to it.

ShadowBlocker
An anticheat that shows its work instead of shouting.

Score and weight
Every violation adds points and the score drops ten a minute, linearly, because that way you can count it in your head.
Evidence, not accusations
Measured, expected, threshold, with the unit next to it: “fly (0.42 blocks/tick, expected 0.31)” can be argued with, “cheating” cannot.
Where it does not check
Creative world, double-jump arena, a region where staff launch people for fun: insisting there only reports the server itself.
Eighteen exemption windows
After an event that makes measuring anything sensible impossible, the checks pause for a moment: that is why chat does not fill up.
Three screens
A chat list scrolls away exactly while more alerts arrive; a window stands still, and can be read calmly.

What it is ShadowBlocker
Nineteen checks, each tunable on its own, each carrying what it detects and what confuses it. Every alert states measured, expected and threshold, with the unit next to it: that is what goes in the ban reason.
Un anticheat si giudica dalla facilita' con cui si puo' controllare il suo lavoro.
