He may be trolling, but it would be fair to say that your comment was:
a) bitter and cynical
b) implying a specific major form of cheating
c) implicating a specific well-known player in the above cheating
d) beating a pretty dead horse
Yeah the source and the motivation for posting were both bad. But the information isn't too far off.
Not that you need to be banned for being cynical or anything, you're all right. Just saying, the magnitude of what you posted shouldn't be dismissed, and that it was right to point it out.
But you're right in that none of the above changes the fact that DD is a fucktard.
