One can be well assured these free forums are under a fair amount of surveillance.


Perhaps you are "assured" of that. But you don't speak for anyone else. I think the idea is preposterous.
I have no doubt these forums get run through various NSA spying tools, but the idea that this board or any other would specifically be under surveillance - that the government cares what you post here - is nothing more than an exercise in delusional self-indulgence and narcissism.
Nothing that is posted here is important enough for anyone to care.
