I Typed Tonight On Multiplayer And It Replaced It With A Swear Word

So, I was playing on a multiplayer server, then I told everyone I was recording tonight, and when I typed tonight, It replaced it with a swear word, I think the server made it that if you swear you burn, anyway, red writing popped up on the screen saying you swear, you burn, I started burning, Then I just left the server, I came back in! I was still burning so I ran through a portal with water thinking I would wash up, I did because the minigame was offline, anyway! I was so enbarrassed! Here is the server IP
