back when i ran a minecraft server, (2012-2014) i had to install a censorship filter, which i hated doing. I tried getting clever, making it do automatic substitution words for the most commonly used things.
Then they’d use spaces. t h e w o r d would be like that.
So I captured the single spaced ones.
But after that, I let it be. If they used other combinations of spaces, other letters, etc, – Nobody could argue that I didn’t work on the issue and they got to feel clever for beating the system. Win win.
