Commands for command blocks on Minecraft reddit?

I've tried many times to find interesting commands for command blocks in Minecraft. While searching, I keep coming across reddit posts such as:

https://www.reddit.com/...nd_blocks/

Unfortunately, I can't find the command on the pages that I have to copy to paste it into me.

I looked and just can't find it, maybe someone knows where I can copy the command

Where does it say that you can do it that way or that there's a command to paste somewhere? If I have worked on something for a very long time, I might not make everything immediately available to everyone. This is just a showcase and not a tutorial

Sure it is, I also know that others have it because of that, I just can't find where.
