"https://counter.theconversation.com/*/count.gif?" (iframe on the bottom of page) is analytical tracker which must be removed.
- Not only the iframe is hidden with CSS rules, but it's inside an anonymous block that it's not identifiable.
I see your regex, but it's not a reliable way to resolve. What if the iframe contains a useful content from https://counter.theconversation.com/ and your regex deleted it?
