How "Vote to Dismiss" is designed encourages abuse.

Can you really say that SE designed the system in such a way to intentionally make players want to be jerks with it?

Why are you attributing system malfunction with developer intent? Have you ever written a program in your life? Users can and will do unexpected things to a system after you create it.

Systems are not neutral arbiters. They are a human concept, designed by human beings and created with an intent to produce human behavior. They are almost always methods of control. Sometimes they fail their intent by producing unwanted behavior.

(FWIW - human beings and living creatures in general are hard-wired to be empathic creatures. We don't become selfish until external stimuli motivate us to be. So when players act toxic toward each other - you can almost guarantee it is the fault of game design, not 'human nature'.)
