Some can, Selenium or other browser automation is sometimes used in bots. Really, any headless browser can be paired up with some automated QA toolkit and turned into a rather effective bot. All that has to happen is for the bot to load the page in headless mode, then issue the keystroke events to the specified elements.

From my experience most don't as it costs more money (ressources). For me a hidden input with some math solved by Javascript got rid of 10 spam contact requests per day to actually 0.

However of course, the larger a page gets the more dedicated the bots get.

But for the plain porn/russian spam it helped.
