I did read the blocking of his account to mean that he was detected in some form. You may not agree with my reading of that letter, and I certainly don't agree with mrtron's reading of the letter, but that's why I asked people to read the original letter anyway. I never said that it was not a case of responsible disclosure. I simply don't know, the evidence at this point seems insufficient to support either conclusion.
