For example, people on Reddit asking redundant questions and give equally redundant or unhelpful answers.
Whenever every ‘What’s the worst show you’ve seen?’ is asked, you’ll get 10,000 “Kardashians” answers, which is just easy karma farming.
If someone posts in a community that’s geared for something like opinions, but someone elects to just go on a full scale rant instead.
Experience has shown that too much blue-eyed-ness and openness towards trolls with bad intentions ruins a space very quickly. I can understand people want to put some thought into avoiding this before it happens.
