I wonder what the effect of a protest by millions of YouTube users adding “五毛” (“50-cent party”) to comments for a week would be? No additional labor, since deletion is automated, but what other secondary effect costs would be incurred? The comments are stored, and indices updated, so perhaps a lot of compaction might slow the site or cause other problems. What other secondary impacts, if any, can you think of? Also, what happens if YouTube users put “五毛” (“50-cent party”) in their profile descriptions? Not advocating this mind you, but thinking of it as a thought experiment. It's useful because it is a real world case of where a protest might incur an indirect DDOS (IDDOS?), and how can we prepare a site we manage against that kind of protest. Also, I am firmly against any kind of censorship that isn't clearly protecting against the equivalent of someone yelling 'fire' in a theater.
