Confused about repeated occurences of URL/essayorg/topic/ showing up as 404 errors in our site logs

[linkjuiced]

Working on a Wordpress website, https://thedoctorwithin.comScanning the site’s 404 errors, I’m seeing a lot of searches for URL/essayorg/topic, coming from Bingbot, as well as other spiders (Google, OpensiteExlorer). We get at least 200 of these irrelevant requests per week. Seems like each topic that follows /essayorg/ is unique. Some include typos: /dissitation/Haven't done a verification to make sure the spiders are who they say they are, yet.Almost seems like there are many links ‘in the wild’ intended for Essay.Org that are being directed towards the site I’m working on.I've considered redirecting any requests for URL/essayorg/ to our sitemap… figuring that might encourage further spidering of actual site content.

• Is redirection to our sitemap xml file a good idea, or might doing so have unintended consequences?
• Interested in suggestions about why this might be occurring.

Thank you.
