Reduce but not eliminate.
When I set up a new e-mail account on my ISP for my son I used a pretty common name so he could remember it (he was only eight at the time). This account was spamed with hardcore porn 10 min after set up. Talk about pissing me off here I am showing my kid how to access his e-mail and what the first message that comes across “do you want 4 inches added to your c#*k”. But it’s all good because it led me across the internet looking for solutions and to AO believe it or not.
