Stevie: As this is an international site people should be aware that some words don't travel the Atlantic well. Words that are taboo in the UK are acceptable in the US and vice versa. Ideally all these words should be best avoided. The English language is rich and you don't have to use vulgar words or colloquialisms.
The way these words are used and in what context also go towards the moderating decision. Most, if not all, public board moderators are aware of the variations in meaning of different words and act accordingly.
There are many ways of asking someone to 'go away'. Unfortunately, the variation you chose was unacceptable.
The bottom line is, be nice or don't post.

I also think if this subject is to be pursued further then it would be wise to take it to an appropriate fellowship or privately, away from public boards.
