So quora seems to have gotten this:
Increase the user engagement by encouraging questions, even if they are trolls.
I had a lot of enthusiasm when I joined quora, then I realised there's some deity praising ritual that happens there, and then there are waste troll questions.
To think of an answer for a question takes up time, and quora moderators in their infinite wisdom delete them. Bummer!
In fact, a girl got racist, and when I opposed her, Brilliant Quora Moderators deleted my answer. I appealed but no action was taken. Next day, I saw again one of my answers collapsed. If this can happen to one of my answers, and comments, it can happen to my others answers as well. I don't have any time to write answers, only to be deleted. So I have deleted my account and I'm not going back to that hellhole.
Typical example of questions:
1. What does Mr. X think about Blue Blood on Quora? (X graces with an answer, and everyone goes stoned)
2. Is it okay to eat our own children as stews? Or, should they be only fried? (Some wise guy will come up with an explanation on how famine induces cannibalism and it's okay to have children as dinner).
3. How much is 2 + 1? Someone will solve it with multivariate probability and calculus with thermodynamics theory, and will receive 13 billion votes.
4. I wanted to crack IIT (Indian Institute of Technology) but got into MIT (Massachussets Institute of Technology). Should I join? (Someone will tell how IIT > MIT and why he should drop).
5. How is Modi different from Trump? Or, Why does Trump have his daughter but not wife as first lady? (some Trump bashing)
Conclusion: Stay away from this murk.
