Whether or not you talk like this to your friends is not the issue, the issue is forum rules, if you are angry, frustrated at anything there are better mediums to use then taking the use of using profane language, profane is the term to describe bad, cursing or swearing words which the above are, this is against forum rules.
Does that means "bullshit" and "damn" words too are banned? And bad words... in what context and what words? I am used to words when i'm happy too or overjoyed. Is it just F word which is causing the trouble ( and it gets itself censored too) or anything else.
