These are fairly experimental and may affect performance or stop working at any time. Feel free to comment if you have any better implementations, I tried to be both as specific as possible and follow reccomendation from the documentation, though I am just a guy.
The files are (at time of writing) are .ubo files (for UBlock Origin) though I dont believe this is an official file name.
All these were testing using AdNauseum, a skin of UBlock Origin.
Instructions on how to use these located here: https://www.ghacks.net/2014/10/10/how-to-add-custom-filters-to-chrome-ad-blocking-extension-%C2%B5block/ (the particular tab may be called "your filters" or "my filters")
