I'm not so sure about that. A single troll can do a lot of damage. A single person can acquire scripting software ( like the Arrington username ), abuse the page formatting on every page, and destroy the balance of conversation by pissing people off.

It takes the ethos of the entire community to keep this all in check. Some trolls might assimilate, but a determined person would be hard to deal with.

yes, one troll can do a lot of damage. but trolls around here never get the chance, because their accounts are killed swiftly. the editors on this site are much more aggressive about curbing bad behavior than anywhere else i've ever seen.
