After reporting another post from the same banned domain which posted one yesterday, I was wondering whether some additional hurdles could be implemented. For example, how about verifying new members through an SMS with a code sent to an Australian mobile. After all, why would people outside Australia who are not a REP sign up to post bargains? Unless of course they are overseas temporarily, in which case they will likely have an Oz number.
Also, how about when a poweruser reports a deal, it is hidden until a moderator decides otherwise?
Not so sure about the SMS code. Some individuals may not like sharing their mobile number (myself included) just to sign up for a website.
