A mechanic of the game threatens to end the sharing pictures of builds Forever!
Photos of builds, and the texture rotations on each block, gives away the coordinate location of that build.
Recently a number of builds on a server I admin on were destroyed. The one who did it shared with us a video showing how texture rotations in Minecraft give away the coordinates. Here is the video showing it in detail. This threatens to end the social media aspect of Minecraft. Please convert your rotation mechanic to using a real random number, not one based off the blocks coordinate.
Can confirm in 1.17.1 (that the random rotation is based on block coordinates).
