I ran a Minecraft server for 2 yrs (2012-2014) and in about one hour or so, the Aussie and NZ kiddies would come home from school and get on the server and yeah, the language DEFINITELY changed.
I let them talk the way they wanted (I just checked in once in a while to see if there was bullying going on, otherwise, I just kept the server window shut and let them talk about whatever; I ran it like it was their server and had enough admins that I didn’t have to worry about much)
That is… until it was summer vacation for Americans and they were up all night. (aussie afternoon)
WELL… it wasn’t very long before the complaints came rolling in about the language… and I had to put a profanity filter on.
I personally didn’t care WHAT ppl said as long as nobody was being bullied or excessively gross or overly perverted.
But when the American players encountered the Aussie players… yeah. Total culture shock.
So, I had my nephew help me come up with a list of substitute curses that he thought would be funny. They hated the censorship but it qualified as bullying at that point, so I had to respect that.
