If there was a list of things to avoid, tripping E*****n would definitely be on the top of that list.
E******n is a highly secretive world-wide signals intelligence and analysis network run by the Anglo Saxon alliance. It can capture radio and satellite communications, telephone calls, faxes and e-mails nearly anywhere in the world and includes computer automated analysis and sorting of intercepts. You can learn more about it on Wikipedia.
The following is completely unconfirmed but here is a website that offers a list of words which might trigger E*****n. I know it’s slightly paranoid but besides being able to possibly protect yourself, it is also a wonderful list of words to research. It’s basically a list of things that the US government doesn’t want you to know, including the names of various secret CIA operations. And that’s not conspiracy theory gibberish.
