Will say it again guys if people had to have legitimate email accounts to sign up e.g Optus Telstra Netspace TPG dodo ISP. Seems some people are confused between having an Internet Service Provider (ISP) and having email accounts if you have the internet on at home or business you automatically have the use of legitimate email accounts many ISP's allow multiple email addresses per account. So if you share a house and internet cost you can still have a personal email. These guys and bots use the likes of gmail and yahoo accounts and they have multiple accounts with multiple identities. Simple solution to a growing problem.
