Facebook and Twitter comments

Comments on Twitter and Facebook have been brought to our attention and we don't like what we are hearing.   These social networking websites can sometimes be anti-social when certain comments are made.    It seems easy, to many, to make what appears to be a personal comment to a 'friend' and be unaware that the comment is seen by others.
At this moment in time we are not going to mention names, but simply say that comments made without thought can backfire on the writer.
The political candidates, to whom we refer, will know what we are getting at.  Personal remarks are not called for - so perhaps those concerned will be a little wiser in future.
