Unfortunately, this game is quite corrupted. The GMs are not frequently enough online to keep order, or just don't care. Plus, there are tons of immature people, brats, and arrogant idiots who firmly believe that anarchy is their right and that whoever can harass all other people away gets to stay in a map, KS a certain boss that other people have waited hours on spawning, steal a PQ spot, etc. People think its cool to call less experienced players for 'n**bs', to quickly adapt to the chaos and to believe that it is alright to be stupid when everyone else is. There doesn't seem to be any easy way out of this problem, but what we can do until Nexon decides to take action (= never) is to keep fighting for a nice and safe environment and stalwartly avoid spreading this plague of idiocy that so quickly engulfs the majority of this population.
That hackers fail, we can all agree. However, hacking is an obvious, unacceptable crime which is avoided by being very careful with your personal account information and never give it out to anyone when not absolutely necessary. It is quite harder to avoid your main topic - people being unfair to others in the game.
The term "wall of text" only applies to ignorants who do not bother to read their opponent's mostly perfectly valid arguments before immaturily attempting to counter them.
