I have looked back at her posts, and they are blatant self publicising and concerned with commercial advancement.  So that is why I have told her she is banned.
Seems the easiest way.  
I did think about asking her for £300 advertising rates, I am sure that is what she would be charging in the Magazine.
No legal objections – just thought the qiueter that she went away the better.  I can imagine her starting something ‘to save face’.
Just see if the number of visitors goes up as the rumour spreads of her being banned.
