I would strongly recommend the book called: "The Revolution Will Not Be Funded: Beyond The Non-Profit Industrial Complex" It is a collection of essays about the history and function of non-profits in America. If you do read it, feel free to skip the first essay in the book. It is very difficult to read. That other essays are all much better and you will definitely learn a lot about how the wealthy have used non-profits to prevent meaningful social and economic change.

There are some exiles setting base at Raddle and even some posts explaining the situation.
I didn't know of that site, but taking a look at it, it seems like an alternative already set up to what you are calling for.
That would be a hell of a long list! Look at the directory in the Industrial Worker, they have to use some microscopic font and near-zero line spacing to fit it all on one page. :P
No problem. Having used a few services I recommend Mullvad ($30-$40/yr). A good tool the program offers is a dead man's switch which cuts out internet service any time your VPN loses connection, super helpful when downloading torrents and keeps your ISP unaware.
