I doubt it did not do much given it was planned. What could potentially cause a bit of work on their part is if this trolling is done more randomly on an ongoing basis, and not so obvious. Though even then they probably have ways to tell. What might get them really going though is downloading lot of torrents with file names of copyrighted material that's not actually copyrighted material. I'm sure it's not just terrorism they're after.
