This is a healthy link: “http://www.bloomberg.com/news/videos/2015-01-30/amazon-google-report-earnings-bloomberg-west-01-29-”
However, server logs show that TwitterBot requests “http://www.bloomberg.com/news/videos/2015-01-30/amazon-google-report-earnings-bloomberg-west-01-29” (difference is the missing trailing hyphen), resulting in a 404.
Only the correct link is surfaced to the public. Why does this happen? Does TwitterBot crawl permutations of available urls?
