Fairly harsh with your words? Why don't I quote what you said on your FB status??
I believe, 'a dirty horrible b@sta*d' and 'mersey scum' might have had something to do with the reason Worrall messaged you? Not what I would call banter, more personal insults towards him.
I would hardly call, 'come and see me in the pits' a threat would you? Because of course the pits is a common place to start a bar-room brawl, somehow I think not. You seem to be a tad hypocritical.
Personal opinion.
