Something you need to understand about Quora is that the BNBR policy extends far beyond what is publicly visible.

“Violating” it can be as simple as:

• Posting a message someone wrote to you that could be construed as “offensive” by any reader in any sort of light, without first blotting out the message-writer’s name;
• Posting any sort of criticism of a person or political movement, including public figures;
• “Sounding” anything other than completely pleasant and genuine, regardless of whatever someone has written to you first;
• And posting an opinion that followers don’t agree with. I’m saying that some people who have never even approached violating BNBR have been banned because they had differing political or moral opinions and quite literally got reported into oblivion.

Reading your answers, it seems to me that you had a habit of specifically calling people out for things they had done that you found offensive, by name. That alone is enough to get you banned, especially considering you had a tendency to insult them and even threaten violence.

As for your exchange with this trans person, I haven’t personally seen any of the comments, so I cannot hold an opinion, but unless every message you posted was nothing but respectful (and even if you think that it was respectful, one person’s opinion that it wasn’t is enough to earn a violation), I can easily see that being another BNBR violation.
