SnCaptcha

SnCaptcha

SnCaptcha is a time-based anti-macro captcha for EdTools farming worlds. It measures how long each player actually spends farming, and once that total crosses a threshold drawn privately for them, it asks them to prove they are at the keyboard.

The challenge is a menu of four number heads. The player runs /captcha and clicks them in ascending order. Failing to answer in time, or clicking out of order too often, runs a ladder of console commands you configure.

Features

Accumulated farming time is the only trigger. No behavioural scoring, no pattern analysis, no response-timing guesswork, so there is nothing to tune and nothing to produce a false accusation.
A private threshold per player, drawn from a range you set and re-drawn after every captcha. Two players farming side by side are never asked at once, and nobody can learn the interval by timing it.
Only players who are actually farming are tested. Accrued time never decays, so the plugin refuses to challenge somebody who has stopped.
The challenge cannot be answered in chat, by design: a proxy-level mute would stop a chat answer from ever reaching your server. Inventory clicks and commands are the only channels.
The heads carry no readable data. No name, no lore, no hidden tags. Which digit sits in which cell and which skin is drawn are both re-randomized on every open, so a generic auto-clicker has nothing in the menu to read.
A configurable sanction ladder by failure count, with an optional decay so an old failure is forgiven.
Staff alerts in game and to a log file, for a captcha sent, unanswered, failed or solved. In game they are opt in per staff member, off by default, toggled with /captcha alerts.
It refuses to challenge anybody when it cannot present a solvable board, and says why in the console. A broken menu file or an unreadable head texture never turns into a punishment.

Optional integrations

WorldGuard: lets you list regions where the farming timer pauses and no captcha fires. Without WorldGuard the region list is simply ignored and nothing is exempt.
Floodgate: identifies Bedrock players, who are never sent a captcha. Without Floodgate the plugin falls back to the Bedrock UUID prefix, and any failure to detect is treated as "not Bedrock".
