I am sure Geekzone members are too smart to be drawn in to these scams,(investments) but interesting article on SMH: http://www.smh.com.au/digital-life/digital-life-news/beware-24-ipad-penny-auction-deals-could-leave-you-penniless-20120105-1plxc.html
Personally I would ban them.
I am surprised the Commerce Commission permits them to advterise "overstock ipads' etc. - that is patently not true. Even seen this on Geekzone I seem to recall.
I guess its like like lots of forms of gambling - how do you stop a small proportion of people hurting themselves without being a nanny state?
