I got to use a selenium trick I learned writing the @comedy-bang-bang-no-context bot at work today
There are ways that websites can tell if you're using selenium. User agent is only one. Another is that selenium reports a property called navigator with a value of "webdriver" by default, which is overridable to Undefined. Before I figured this out cloudflare was sticking captcha's in my face so many times I literally couldn't log in even if I took over the chromium window manually.
