I honestly did not understand immediately what the article was about. I misinterpreted both the title and the content itself until I was half way through it.
I agree with OP: the term "trolling" is generally understood very differently from how it is used in the article.
I assure you he did not – colleagues and I have been using troll in precisely that way for at least two years. Language is ever flexible. Trolled can mean someone getting you irritated, whether they meant it or not.
