Take a joke, the last thing i would ever sue is an online game.And I got a McAffee, Trend Micro, and google popup-blocker, so i guess that makes 3 from basic knowledge. A good firewall? I have two of three, not to mention a filter.
And from what you guys said, i know its not my computer because i had 2 pop-up blockers and only opened them for pve.spaceo.net, so it wouldn't be likely for a spam attack.
Still if its the sites that you guys said, then why not remove them and put in different ones? It's not that much work.
Anyways,
I don't know how you could sue an online game or websites, seems impossible.
