Out of curiosity, what happened in the post about the FUTO keyboard where there were a lot of messages deleted by moderators?

I’ve commented there

What the heck happened with all the messages deleted by moderator?

And it got deleted. Right now you can only see 4, but I’ve counted 19 messages moderated and the post has been locked.

Why?

Edit: I’ve added some screenshots so that you can see that the posts were not off topic
