Pi-Hole is “a black hole for internet advertisements”. I personally run one on my home network, and have set one up for my grandparents (so my grandpa would stop getting malware and viruses by clicking the wrong ‘download’ button).
I can set one up for you too! Contact me for pricing. Personally, I hate using the internet without it!
This is my all-time favorite project to do with a Raspberry Pi, and I’m glad to see the developers getting some attention in the mainstream!
