Such things didn't exist before Internet, not to this degree.
People like myself can become more resistant to such things but there are too many unprepared for some things.
Also, the South Korean web environment is like nothing in the other parts of the world. Technically much more advanced in terms of average concentration of bandwidth and availability, but extremely savage. At CDFreaks, for instance, I can even see there are some female members though the percentage is very low. There are even those under 20 and even under 15 here. There are people over 40 and over 50 and even over 60 and 70. Such diversity is possible because it is more like the real, non-online world. Being multi-national or inter-national or super-national or global also makes the environment more friendly and compassionate. The first thing we can to do aliens and alien culture is one of the two: try to understand it resist it blindly. Such a learning climate helps people to listen and think more before bashing and spamming blindly on a gigantic scale.
South Koreans on the web is a mob, when discussions are desired. That even helped Mr. Roh, Muhyun to become the president and make some pro-North people get more power. Westerners and Japanese, by comparison, are like thoughtful dolls, if you know what I mean.
What would do if you knew I am saying on this very thread that I am going to commit suicide if somebody doesn't listen and try to understand what I feel? They continued to attack. KBench.com didn't want to be responsible because the boss knew he criticized KBench's way of business often. KBench.com was once worth somewhere about 10,000,000,000 Won, or nearly US$10,000,000. Maybe it was 20 billion, I'm not sure.
