Reddit may resemble Quora, only Quora has one strict policy: BNBR, Be Nice, Be Respectful. And then to survive there, one needs to understand that enforcement is by paid staff, and the volume of complaints is enormous, so they have, perhaps, a few seconds to decide if an Answer or Comment violates policy. They will not investigate the history. The will only look at the comment itself and how it appears. In other words, the real rule, in a practical sense, is "Do Not Look Rude." They do warn before blocking, and they start with relatively short blocks, before banning, at least usually. So learn or be banned! (And it will commonly look very unfair! I was blocked for quoting what another had stated about himself. Unfair!!! He was an asshole!!! OMG!!! But ... once I realized the system and how it worked in actual practice, this was simply the natural consequence of not thinking about how it would look to a clueless mod, overworked and underpaid. Ah, that troll! He was actually blocked before me, and apparently when he came off the block, he complained, the timing was right. But so what? He doesn't matter at all and I think he's gone.
The Smith brothers have been known to file voluminous complaints. Admins will tend to think that voluminous complaints indicate that something must be bad or wrong. So if one is involved in controversy, understand that one may need to be very careful about appearances. Enemies will use them and can lure admins into blocking.
I would not use Reddit for any serious content creation. It's a social media site, full of trolls, but also many nice people. Arguing with trolls will irritate everyone, I recommend against it. I point out throwaway accounts when they troll, that's about it. Where a significant issue is raised, I might address it. I do not attempt to match their extensive verbiage; if I need to add detail, I don't add it on Reddit, but may link to it. See
