@slackz Organising on Facebook is handing a nicely formatted list of all activists, all their contacts, friends and family, their 24/7 location data, browsing history, and a list of how to manipulate them to the authorities.
It doesn't matter how many people are there, it's not worth it.
If people truly care about an issue they'll go to the extreme inconvenience of typing a different URL into their browser to visit a safer site with less surveillance built in.
