I noticed this google ad popping up today....I found it interesting as anything to do with type of activity is FT Taboo:
"New Low Prices
Free tickets and upgrades just got alot cheaper. Top off miles today
www.miles4sale."***
I deleted the last of the website name as I want no part of promoting such a sight. FT might want to investigate whether they can 'ban' that ad from its FT site
