I've written one (in PHP).
For example, do they process JavaScript? I am thinking more of bots that aim to steal emails and so on rather than search engine bots.
Mine doesn't. I believe that most others don't either.
Basically, I'm trying to think if JavaScript where to update a section and add the email address in after page load. Would a bot be likely to process this? Or would they scan JavaScript for email addresses?
They might scan the entire source of the page or scripts for email addresses, but not run the JS code itself. Therefore if you obfuscate the email address trivially (e.g. "fred" + "@" + "example.com") then it would not be picked up correctly.
I realise that this would mean browsers not supporting JavaScript would not be able to see the email address - however, that's another matter.
Yes. Most people use a form for this purpose and have the server send email to an address not provided to the browser.
Or alternatively, get a decent spam blocker and put your email address in there anyway. You can't keep it secret indefinitely.
