What kills imageboards is a lack of QUALITY posters, and hordes of shitposters drive them away.
Let me ask you something, when is the last time you heard anyone mention 4chans /b/? When is the last time you ever even thought about it? Do you even actually still consider it to be a living or dead board? Now that you think of it, does a part of you actually imagine no one must post there anymore?
Hordes of cancerous faggot shitposters killed KC. It killed 4kanker /b/. It eventually destroyed most of 4kanker. It also killed old EC. It is literally cancer. The unrestricted growth of useless cells that serve no other function than to multiply themselves until it kills the host.>>5426
This retard is an excellent case in point. Shitposters eventually drown out all discussions and flood good threads off the board with their unrestricted--sometimes knowingly deliberate--shitposting. It destroys the community utterly. That is why KC literally no longer exists. They are an infection in human form.
The final stages are when it's so cancerous, so awful, so terminal, that even the shitposters themselves cannot wallow in their own filth anymore. A very good example of this is 8kanker's /kc/. That board is literally a dead board. The last time I went there it was such SHIT I couldn't believe me eyes. You see, shitposters cannot exist in a vacuum. They can only continue to exist by attaching themselves to a healthy host. There they drag quality down and begin to multiply, until they have outnumbered all good posters who simply stop posting.
Pic related. They are the faggots that ruin the hobby. Then by the time the original group is not even a memory, they too abandon all pretenses of being there to enjoy the hobby to begin with leaving nothing. They are like locusts.
