Nope, it would not have been prevented by CORS.
CORS prevents reading from a resource, not from sending the request.
If you find that surprising, think about that the JS could also have for example created a form with the vote page as the target and clicked on the submit button. All completely unrelated to CORS.
> CORS prevents reading from a resource
CORS does nothing of the sort. It does the exact opposite – it’s explicitly designed to allow reading a resource, where the SOP would ordinarily deny it.
Even mdn calls it "violating the CORS security rules" instead of SOP rules: https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/COR...
Anyway, this is lame low effort trolling for some unknown purpose. Stop it.
