Operation Troll the NSA? Brilliant. But there is one problem: they might just start filtering text out. I have a solution: use this image with slightly changes colors, e.g. lower brightness, higher contrast, scaled etc. Put this image inside an e-mail and use some possibly filtered words, like ‘terrorism’. Each e-mail should use different set of words to lower probability of filtering everything out. Even small differences will make filtering this picture impossible, because they are likely to use hashes like SHA-256 to compare content, and since images are much larger than text they should be overwhelmed much faster.

Dear NSA

Sincerely, the Internet
