“Maintain” and “sustained” are the key words there. The effort is constant and must be. You only have to get it wrong once, those wanting to slurp up all the data they can about you and pass it on can keep trying and trying and tying, and the effort is much less expensive to them (portioned out over the number of subjects they are tracking or attempting to track) than the counter-effort is to the individual.
