This thread is symptomatic of the UK at present. We have someone who is demanding their 'rights' and asking for another poster be dealt with just because they don't like them. If this happened on the street, in a cafe, pub, dinner party then you would move away from someone annoying you, unless you were looking for trouble.
Here we have one poster, who gives little to the site except raise the complaints factor many fold, asking for another poster who had been, and IMO, still is a good supporter of the site (unless you have not used the Search function), be punished or dealt with presumably with a view to banning him.
Well I hope the COs and Mods have more backbone than our politicians and deal with the complainer who seems to be verging on vexatious.
Know your Rights, but also know your Responsibilities.
