Quora is a spam site and should not be at the top of Google Search results

It seems like at least 80% of Quora responses are long essays copy pasted from somewhere else, that don't even answer the question and are posted by people who know nothing on the topic. Usually they all end with a link to some product or service, and it's clear that these people are from SMM agencies posting spam. This has been going on for years and Quora, despite being a well-regarded company, clearly has no effective strategy to identify and ban such spammers. There is absolutely no value to showing Quora results at the top of any Google search as I'm sure most people just skip over them. Google should classify it as a spam site until they get their act together.
