Anonymity is where little bad actors play. The big ones don't need to be anonymous because their nefariousness is legal, or they don't get prosecuted. See: waves vaguely in the direction of the US government.
That said, the recent waves vaguely in the direction of the US government has demonstrated the weakness of legal restrictions on the government. It's good to have something you can point to when they violate it, but it's too easily ignored. There's no substitute for good governance.
