Uses mutation observer to take action when elements added to page. Looks for ads based on Spon appearing in non hidden elements!
Only tested in Chrome - unsure of conditions that might change (e.g. classes)
Utilises mutation observer to parse added page content for ads.

Generic retry wrapper was poorly scoped, effectively stopping it from resetting the tries count anew after a success.
I also note that the mutation observer isn't aggregating dom changes as much as I'd like - so it's a good candidate for being debounced so it collects all the changes and performs the ad clean only once after dom changes have ceased.

Suggestions welcome.
This is for my own and others academic amusement - ads are only hidden and not prevented from downloading in any way.
This script may not be high performance as I fiddle with it and could have a high cost to your CPU and or MEMORY whilst running.
