Hmm. I think they are more active in targeting people rather than gathering places. Gathering place are where they pick up leads, then they follow individuals who deviate from their goals and use individualistic tactics to influence them, usually using methods that are difficult to detect.

Intelligence agencies are not dumb. They don't want to be seen or heard. Their mission is to gather intelligence and influence behavior while remaining undetected. Once they've been made, they've failed in their job. Don't expect many responses from them here.
