APG - Your stance is clearly based on your strong personality, and the fact that personal abuse does not appear to upset you.
That is all fine and good, but not everyone has that approach, and nor should they - vive le difference.
On that basis, people who are upset and / or offended, have a right to some level of protection because a free-for-all does not really benefit anyone in the long run.
As far as AB goes, it is run and offered as a family site, and young children can and do access it, and on that basis, the more 'robust' language and observations may be deleted by Moderators.
Of course the Moderation system is not perfect, no system is - but it enables the AB to function for its purpose, which it has been doing very nicely, and well before Twitface was a gleam in its inventor's eye.
The rapid rise in social media has meant a corresponding rise in its misuse and I don;t believe that answer to anonymous abuse is either to put up or shut up, as you appear to offer.
I can only speak for the AB, and I am perfectly happy to be subject to the same moderation as everyone else on here (contrary to the persistent belief to the contrary of a notable few!!) - I believe it enables the site to function correctly.
As the site approaches its twentieth birthday, it has to be doing something right - a moderated Q & A site would appear to suit a lot of people like me, who would not venture onto Twitface for a gold pig.
