引句：
Knowing that Second Life events like this were sometimes plagued by 'griefers'— troublemakers who might appear in outlandish or offensive attire, create protest signs that could fill the entire screen, or otherwise disrupt activities — Ms. Pritchard called Mr. Gingrich's office. She offered her company's virtual security services to a confused aide.

This isn't because I believe griefing is wrong. I actually think a little online anarchy is a positive thing. Griefing demands critical thinking from the griefer and urges technological improvements in everyone else.
