Well, that's unfortunate. I get that owners/employees/mods can delete content and ban users on their site, but I don't agree with forcing people to be a participant in that punishment.

There was another site that I posted on years ago that had pretty strict politeness and no politics rules. Often, instead of deleting offending posts they would selectively censor content in them, often creating confusing and incomprehensible exchanges between the posters. They wouldn't tag messages that they edited, the only way you knew was that something you read earlier was now chopped up.

I stopped posting there because it became so pervasive and annoying to read gobbledygook. While a site has the right to remove their content and ban someone, you don't have the right to change their words. I lump "you delete it and apologize" rules in the same category.
