They deleted probably around 100 of my posts, because I included a link in my answers. Which was complely related to the answers I provided. They claimed they don't want people endorsing themselves. Why in the f--k would I answer questions for free, while Quora collects BIG TIME, when I can't even endorse myself. It was a link to something I'd written, which further answered complicated questions. They don't want people directing traffic away from their site, but they have more than enough traffic. And it'll probably cost them in the long run. It's possible they deleted the posts for personal reasons, but regardless they're sick.
