Since the Edward Snowden revelation it is public knowledge that the intelligence agencies of the 5-eyes countries, especially the NSA in the US and the British GCHQ, use mass observation to monitor all electronic communications including social media. It is also known that they use
agents provocateurs, and the like, to manipulate discussions on social media. I have also no doubt that they have the technical means to find out the real identities behind user names on Pofo and other social media.
Having said that, Pofo is far too small for them to bother. They focus their efforts on big platforms like reddit. To monitor and/or manipulate every discussion forum on the net would require too many resources. I think we probably have a couple of Russian trolls from time to time. I really don't know why they bother. Their bias is so obvious. But there are probably no paid NSA shills in this forum, plenty of free-lancers, though.
Trump is ruthless and as unrefined as former Soviet propagandists when it comes to manipulating the media. His attempt to ban Tik Tok because their users messed with his campaign rally is silly and counter-productive. If he were to be reelected, a crack down on social media will likely be the least of our worries.
Anyways, if I'm not mistaken, Pofo is based in Europe. The European Court of Justice has recently ruled against transfers of European data to the US. The EU will be the last bastion for protecting our freedom. Don't mess it up.
