Once, when playing Battlefield 1942 on a Punkbuster secured server, someone hacked into the coding and placed a huge, horrible virus on everyones computer. Yep that seriously sucked. Whenever i connected to the internet on the PC, i'd get random rap songs playing through my speakers, or have pop ups popping up at 50 explorers a second. Not even some guy from India working for McAffee was able to fix it. So i tossed that comp and now i have a shiny new macbook pro. Life is sometimes good like that, especially when it give you lemons that magically turn into apple products.
The point of this story, you ask? Some hackers can financially damage you (1.3k for new macbook pro, but well worth it!), so its fine to hate them, when they do it online, for the sake of hurting others. Why people can do this to another human being when it profit them not, i cannot explain. For the sake of lawlz? Maybe. But its fine if its done offline, and for the fun of everyone.
