Please explain "surveillance dragnet" - I didn't see any evidence of that in the translated article. I saw some "I wonder how they found my stage name", but unless he's taken some large precautions, that doesn't seem too far-fetched for Google to handle...
He talked about them knowing about all his shows, stage name, and about facebook relationships. Translation is sketchy but he seems to be making a wider point that they knew about a bunch of stuff that would only be known by fairly broad and deep surveillance (as per the title of the article) and then applying a distorted interpretation.
