There used to be a web site called "Throwing Sand into the All-Seeing Eye" which listed a long list of possible NSA-snooper keywords, such as military classifications and code words that could be sent for fun across the Internet for sole purpose of being flagged by the NSA.

I imagine they(tm) would have countermeasures for this kind of thing, given that once they catch a keyword, they know it's source, and have some idea of the kinds of patterns which are likely to be real communications. The Web site probably went straight into a junk filter, which would make it an ideal place to post your secrets from then on :-) - James.
