A) Run a tor exit on my Android phone, unlimited bandwidth unlimited power just to fuck with them.
B) I block every *king ad I can by running the phone's data through an encrypted VPN to home which which has a spam filtering box. The data will be split up WTF knows how as it's some black magic a kid made that will pick the 'most available' VPN depending on what it thinks is fast or high quality. It's a blade server and it's some linux concoction but I do not pretend to know what it is. I use six VPNs on two business DSL (*sobs*) links.
I'm only a power user of Linux. Most of that is to serve porn for cash but the rest is some clowd stuff.
