I think it might have been physically harmless...at least on the macroscopic scale. But if those particles start becoming charged, you get moving charged particles creating magnetic fields, possibly plasma...perhaps she only makes it as hot as, say, the plasma you find in a plasma lamp, but if she lets it all go, you end up with a spherical burst of charged particles.
It might not be enough to be a hazard to living tissue, but it'd wreck hard disk drives and semiconductor chips.
So I'd be willing to bet "grounded" doesn't just mean punishment...it means a faraday cage.
It's like putting a small dent in spacetime in the same way actual mass does. That "false mass" field is what makes the dent, and the "manipulated gravitational field" is the result. It acts like a kind of custom-made gravitational trench, pulling the plasma stream into one neat line.
On a guess i'd say that you censor stuff from other peoples documents and you redact stuff from your own. Also possibly you censor stuff you don't want to be said/written, you redact stuff you don't want to be heard/seen by people without proper clearance.
Censorship is the suppression of speech or other public communication which may be considered objectionable, harmful, sensitive, politically incorrect or inconvenient as determined by a government, media outlet or other controlling body. It can be done by governments and private organizations or by individuals who engage in self-censorship. It occurs in a variety of different contexts including speech, books, music, films, and other arts, the press, radio, television, and the Internet for a variety of reasons including national security, to control obscenity, child pornography, and hate speech, to protect children, to promote or restrict political or religious views, and to prevent slander and libel. It may or may not be legal. Many countries provide strong protections against censorship by law, but none of these protections are absolute and it is frequently necessary to balance conflicting rights in order to determine what can and cannot be censored.
Redaction is a form of editing in which multiple source texts are combined (redacted) and altered slightly to make a single document. Often this is a method of collecting a series of writings on a similar theme and creating a definitive and coherent work. "To redact" later came to be used in the sense of selecting from or adapting (as by obscuring or removing sensitive information) a document prior to publication or release. In the early twenty-first century it has become a euphemism meaning "conceal from unauthorized view; censor but do not destroy". The word may be used in relation to obscuring or deleting specific information, rather than editing an entire document; e.g. a court may order that the names of people be redacted (from a document).
My conclusion: Redaction is a form of censorship. Which means both terms are correct, although Redaction is the more precise term.
