I admit defeat; here is
Vanquisher, I have narrowed down the people you could be:
It is, in all likelihood, Jeff S. For the vanquisher has never commented on his blog, and speaks like him.
This is the vanquisher's decription.
I would also like to mention that, inadvertently, Tim helped me with this.
The Vanquisher of Anonymous (VOA) was a clever fiend. Sam thought of him as a "he" but wasn't entirely sure. He was quite peaceful most of the time, which is why Tim referred to him as a "mockingbird". He could act as a policeman of some blogs; when someone came on constantly commenting under a pseudonym, he managed to identify them almost always correctly.
His face was the white type of blog comments, his name was the pen name he assumed.
He was clever, as his style of writing was unlike any other. He knew HTML and apparently about how people were trying to pin him down.
There. That's all you get.
