Thank you for actually spelling porn. This whole thing around altering spelling to avoid blocking which I presume comes out of other apps has gotten to be quite annoying.

"Pr0n" is classic internet slang that predates onerous censorship let alone "apps".

Right, the form to deal with onerous censorship is “corn”.

It absolutely came from censorship. IRC chat rooms and PHPBB message boards with blacklists of words that would get starred out. Hoping it wasn't implemented with substring match so typing "shell" didn't come out "s****".
