Description of the issue:

I am currently building a large farm. I used litematica to copy one section of the pattern I wish to replicate for the rest of the farm and upon trying to place blocks with litematica's built-in "easy-place" mode, I was kicked for placing blocks too fast. Easy-place mode essentially allows us to hold right-click and interact with "ghost-blocks" to help place blocks faster in the pattern you saved to file.

When you pair this with fly, you can place blocks very quickly. The issue is that anti-cheat detects this as "fast-place" and kicks you if you move faster than flying speed-2 or if you try to sprint while walking speed-10.​

Reproduction instructions:

This can be reproduced by using an auto-clicker or with litematica.
If you use an auto-clicker, the repro steps are as simple as turning the delay down to 50-100ms and placing blocks in your town.

The following steps are how I reproduced this with litematica.

Pre-reqs:
For my specific situation, you will need to install litematica and once installed, enable "easy place" mode via the litematica config (by default you can press M when in-game).


1. Copy a section of the world using the tool. Ensure it's at least 50 blocks in length to easily reproduce the issue.


2. Paste the copied section into the world wherever you like.

3. Ensure you have matching resources in your inventory that would be needed to place onto the pasted schematic. For example, if your schematic needs dirt, ensure you have dirt in your inventory.

4. Fly at speed 10 (or sprint while walking speed 10) and hold right-click on the blue blocks to start placing them.

You should get kicked within 5 seconds.​

How many times did you recreate this:
