These 'punishments' need to change
It's time that they had the power to be able to dish slightly more appropriate punishments along the lines of:
"The ASA ruled that Groupon be banned from carrying out any form of advertising in mainstream media for 12 months, followed by a 12 month supervision period where all new marketing material must be vetted by the ASA before release and any expenses for carrying out this must be paid for by Groupon. The ASA also started the initial proceedings for a class action on behalf of any customers purchasing a product during this period based on the misleading claims"
And double those penalties for anyone making claims backed up by fraudulent 'science'. Until repurcussions of this sort become viable, those marketing types will never learn.
