Where does the small footer ad show up and where does the thread ad show up on the page? (preferably would like to see screenshots but describing is fine too)

Just log out and you’ll see

If i remember correctly, Footer ads shows up at the bottom between the "quick reply" box and the footer. Thread ads show up between the thread post and the first reply

Or... open an incognito tab 😝

He can't see thread ads while logged out anyways. Only un-upgraded members can see them

You can also open up an alt browser which you might not have logged into HF with in order to view the footer ad. The inline thread ad isn't that great to be honest, that's why it's so cheap. The best ad by far is the header ad.
