Years ago, an old version of Wordpress got exploited on one of my servers. I learned to keep it upgraded to the latest stable version. It's easier now that the script can update itself (with the right plug-in, at least).
Ive never had a blog hacked before but i have had a forum hacked , it was an old PhpBB forum which it was totally my fault, there was warnings saying the script was unsafe and i should upgrade but being very new i just thought " why would it happen to me" lol
Two months later i no longer had a forum, lesson well learnt id say :nerd:
