Hello Zivush: Yes, the headers reflect proper 404s. I've tested them through HTTP status checking online tool. I also checked by fetching the URL as Google Bot. Whenever there's a proper 'Page Not Exist' - the site generates 404 status page.
While we continue to have proper 404.php; I've 301 redirected the problem URLs to their correct URLs (at least all those faulty URLs generated by Disqus. Those 404s generated by removal of unwanted tags have been redirected to homepage. For all other pages; there's a proper 404 error page.
