I reckon bitcointalk might be under heavy surveilance before because there were many radical libertarians. At present, not anymore. Too many account farmers and spammers hehehehe.
Yeah.. when I first joined Bitcointalk in 2012, a lot of the users were Libertarian (including me) and some of them were quite radical. But back then, most of the users were ideologically driven. Very few of us thought in 2012 that Bitcoin exchange rates would go up by 4,000x. Then we had the bull runs of 2013, and this attracted the money-minded users. A very few of the Libertarian users of 2012 are still here, but I am noticing their posts less often nowadays. Many of these accounts have gone dormant. A few might have got hacked and taken over by spammers.
