While it's sadly likely that your communications have passed through an intelligence agency at some point, it's usually difficult to know just who got your data. However, you now have a rare opportunity to find out. Thanks to a ruling that the UK's GCHQ illegally spied on people using NSA databases, advocacy group Privacy International has posted a simple web form that lets you ask if you were caught in Britain's law-breaking dragnet -- and, as you might expect, petition against mass surveillance. This won't provide the most comprehensive results (you should use the official form if you're really worried), but it should still lead to GCHQ purging the relevant records if there's a match. The only big problem? The request is limited to the past data covered by the ruling, so there's no guarantee that you're truly off the radar.
