Evil Captcha
Evil Captcha replaces a plain verification step with a series of image puzzles that grow harder as the player passes them.
What it does
Each challenge asks the player to click the boxes that contain an X, in either a single cohesive image or a grid of small images. Single-image boxes present one picture to read at a glance, while multi-image boxes show several small tiles that fade out over time, and a higher difficulty shortens the fading and raises the accuracy needed to pass. Image pools also change with difficulty, and a classic slide puzzle is available as another challenge style.
Difficulty is tracked in two parts. A global value is shared between all players, so the server's history affects everyone, and a local value rises each time a particular player passes a captcha. The final difficulty combines both. Evil Captcha requires Fabric API and is released under the MIT License, but it is not open source. It runs client-side only, so servers and other players do not need it, and files exist for 1.21 – 1.21.4.
Key features
Single image boxes
A classic captcha layout presents one cohesive image, and the player clicks the boxes containing an X.
Multi image boxes
A grid of small images appears instead, with fading tiles that become harder to track as difficulty rises.
Classic slide puzzle
A sliding tile puzzle is included as another verification style alongside the image challenges.
Shared and personal difficulty
A global difficulty is shared between players, and a local value increases for each player who passes.
Difficulty-driven image pools
The set of images drawn from grows or changes with difficulty, so later challenges differ from early ones.

Use cases
Joke verification on a playground server
Players who want a comically hostile check before entering can use the mod as a novelty verification step.
Solo cursed playthroughs
Single-player runs can use the escalating captcha as a recurring obstacle that tightens as the player progresses.
Who it’s for: Players who want a deliberately annoying verification step in single-player or client sessions, and people who enjoy cursed minigame mods built as side projects.

What the author says
This mod is obviously not serious btw. Not a safety measure, just a small funi I have some more ideas as well, those were too ambitious for a quick joke side project though. Maybe I'll add them in the future There is a Trick to some of them
