Forumotion doesn't want any insults. If you use fuck, you will be banned for a few days anyway.
If you say: "Oh shit, this is horrible"
"shit" is technically an insult, but I have never banned anyone for that, because that would be ridiculous.
This was the obvious part, but the question is, if someone who said:
member X supports murder, or member X likes Hitler and so on. If that certain person has never said it, you shouldn't say it either, because it is considered slander and could technically result in a ban.
World Republic will prevail!
