"You have been trolled. You have lost. Have a nice day."

This nonsense is a popular subject line among trollspotters suffering from a bad case of Jargon File Disorder and a limited sense of humor. IMHO it's not about "winning" or "losing" anyway, because a troll is an interactive performance piece which depends on audience contributions. A good audience provides a feeding troll with more material to riff on. If they make the thing work, how can they be "losing"? It's a partnership, an ad hoc conspiracy of entertainment. If everybody gets pissed off and acts crazy, everybody wins.
