I would like to learn more about how selenium works. And to specifically answer the question: is it possible to know if someone is programatically accessing my website at a low rate using selenium webdriver?
edit: this is quite related, but it is dated Selenium Webdriver is detectable
Also, there is a recent specification for webdrivers that includes a webdriver-active flag http://www.w3.org/TR/webdriver/#dfn-webdriver-active-flag
