I think at this point, it would be pretty naive to assume that we (specifically we) are not on someones radar. Our comments are public, and available to all. I would assume our PMs are available to those with the motivation to retrieve them. Our email. Our cellphones. That's why Charles Oakwood left us when he did. He was wary of the scrutiny.
There's no point in paranoia. But we know that it is possible for agenices and hackers to spy on the most assumptively private communications, and we know that to our own government, we are extremists. Whether we merit being on their radar or not is a matter for speculation.
We should all move forward with the assumption that whatever we say is looked at.
