问题
This morning when I opened my heroku app in the browser, I noticed a banner advertisement was placed on the bottom. I added an instance (as to not be a free plan) and restarted my server, and it was still there.
I dug through their knowledgebase and stackoverflow, can't figure out how to remove these. Right now I am removing them with JS, but the goal is to not receive the extra load / advertisements.

Heroku will not inject adds into your site whether it's free or not. As mentioned in comments to your question, you should check whether it's something that's done by the network you're on. Maybe try accessing your site using https (i.e. https://paddlar.herokuapp.com/rivers) - with that, the network should not be able to modify responses.
