EvilEmail is a small thing I use for individual randomized email addresses unique to specific services.
I don't have any instructions yet, this is more or less a code dump, if I get requests I will probably make some instructions.
Please tell me if you would like for me to make instructions via a44e65fe-312a-486d-b5da-a51a2a62f6a6@email.cynthia.re or Twitter: @bitcynth.
This was inspired by a very similar thing a friend has setup.
I also based a lot of the app script ideas on my friend Ben's GeoIP Tagger.
