Anything posted on the CIA website will be thoroughly analyzed by state agencies that are well funded and well equipped to find shenanigans. If the CIA were really doing something to US citizens via something on their public site, it would come out very quickly as it would be an embarrassment to the agency.
Unless you mean that the mere act of visiting the CIA website would be suspicious because you are in a country that might frown upon that, like China? But wouldn’t the CIA site be blocked there anyway?
