Because they always delete questions asking why a specific user was banned. One reason is for the privacy of that person. There are probably other reasons as well.
Edited to add: There’s no way to get a really good answer to a question like that. Quora will never give any kind of official answer, the banned person isn’t able to answer, and everyone else is just guessing. I think answers to questions like that are at a high risk for BNBR violations and are likely to mostly be rumors and gossip.
All true. The instadelete is odd, but as Sierra Spaulding pointed out in comments (https://www.quora.com/Why-is-my-…), questions about bans are reported vigilantly by Quora users, and most of them are deleted quickly. Quick reporting is likelier.
- Marc Bodnick’s answer to Will Quora Moderation explain why a particular user was banned?
- Why doesn’t Quora inform users of the reason(s) they are blocked or banned?
I have, after a lot of hesitation, started posting users’ own statements as to their bans on Necrologue. BNBR still applies there, as does a ban on speculation. Users’ own statements, I believe, are exempt from that.
