Already have, it only got responses from people trying to suck up to the staff. I'm done arguing about it anyways, I could care less about what goes on the server. It just annoys me to see people buying unbans for stupid bans.
So I understand your logic, you think it's a stupid rule because it's "just a book" and "it's not like everyone on the server can see it."
However, You Also have to understand that there has been many cases where player's use profanity, cyberbully, harass, rage, advertise, and many other mutable offences in guess what? Books and signs! One of my older friends was banned a long time ago for advertising on a sign. It doesn't
really matter where a player breaks the rules. Any player that does not follow or rules whether it's in global chat, rp chat, PM's, Books, Sign's, block placed messages, etc. Will be appropriately and fairly punished by our staff team. Most players get perm banned when they are caught bypassing a mute, this punishment is very nice considering the other punishment the player could of faced.
Also there is no 100% Given that a player would follow the chat rules during a mute when they use books and signs. We do not moderate players 24/7, this isn't Minority Report.
Player was punished fair and square, if you don't like it then as Trenly etc have said, make a suggestion case as to why that punishment should be removed. As i said before a ban for a couple days is nothing compared to the normal punishment for bypassing players.
