Do you really think they haven't developed a spambot to decipher your hidden code and hijack your email address? Maybe, just maybe, spammers are good at what they do and macheist isn't perfect in protecting your info. No email is really safe unless you don't give the address out to anybody whatsoever, which makes it fairly useless.
The chances of someone randomly coming up with my macheist email address by inserting a tertiary domain into the mix, that just happens to be one of 50 or so that I created.. . . yeah, I find the odds astronomically low that a spammer would have done that. Perhaps you are giving yourself too much credit.
I can respect that you want to defend macheist and all, but the bottom line here is that there is a security breech where someone distributed the macheist addresses. It may have been a person who had access to the data, dumped it, then sold it, or it may lie with one of the third parties that macheist provided my email addy to (if any), I don't know. But yes, someone has caused macheist buyers to get more spam then they were getting, and honestly, that will probably mean the end of supporting this program. If my email address is not safe, what kind of guarantees do I have that the rest of my info is not safe?
