It's not my personal responsibility. It's actually everyone's. Think about it like this:
Skuzzy could not physically read every single post on this forum, even if he didn't need to eat, sleep or perform other human activities. Thus, he added the report button under for us the to do leg work for him.
And yes, I call it in if it breaks the rules. They are there for a reason, so that flamewars don't start and that this place doesn't devolve into a wild melee. Look at flamewarriors, they are the result of no rules being posted.
Furthermore, by signing up for this forum service (which HiTech provides at no cost to us), we agree to abide by the rules. If some of us stray from the path of controlled discussion, others will help them get back to it.
