Science
I will explain for the benefit of newcomers to the forum a little of what has caused this paranoia as you describe it.
In the past we have had members join this forum under several different names for the sole purpose of causing upheaval. Why else would you want different aliases?
Eventually they have been found out and removed from the forum.
In your case you have joined this forum, only to post on two threads where you can have a negative poke at Birmingham. Why have you not posted on any other thread? Do you not have any memories of Birmingham? You have only lived in Sheffield since you attained your position there, so surely you have memories of Birmingham?
