The hyperbole is helpful.

First they ban accounts and sometimes delete them to make the person disappear without a trace, and secondly they prohibit you from asking why certain people got banned. This censorship prevents people from acknowledging that certain people existed.

Criticising Quora on Quora will get you banned without prior warning, and in some instances have your account deleted without a trace.

And when you're banned or disappeared, nobody is allowed ask why that happened, as those questions get censored.

Think of it like this when you criticise Quora. http://upload.wikimedia.org/wikipedia/commons/9/91/Voroshilo... http://upload.wikimedia.org/wikipedia/commons/b/bd/The_Commi... And then being censored when you ask why the person force disappeared.
