It is natural to think of the assembling of a profile, an account of a person built from their records, as a task with an end: the work is done, the picture is complete, the file is closed. In serious practice it is not like that. A profile, once built, is not finished. If it is to remain useful it is maintained, and the maintenance is as much a part of the work as the original assembly.

The reason is simply that the subject of a profile keeps living. A person's circumstances change. New records are created: a new transaction, a new role, a new connection, a new mention. Old facts cease to be true. A profile built at one moment begins, from that moment, to drift out of date, and a profile out of date is a profile of declining value.

So a profile that matters is revisited. The records are searched again, the new entries gathered, the picture updated, the changes noted. What was once a single act of assembly becomes a standing process of refresh. The picture is kept current deliberately, because currency is the property that makes it worth having at all.

This has an implication for the person who is the subject, and it is worth stating plainly. A change in a person's circumstances is not a private event simply because the person experienced it quietly. If it created a record, it is liable to be picked up the next time the profile is refreshed. The lag between a change and its appearance in someone else's account of the person is a matter of when the refresh happens, not whether.

It also explains why a person's own privacy work cannot be a single act either. A position assessed and corrected once is correct as of that date. But the same forces that keep an outside profile current, the steady creation of new records, are working on the person's own exposure. To meet a maintained profile with a one-time effort is to fall, slowly and certainly, behind.

The clear conclusion is that exposure is a standing condition on both sides. The account others hold is maintained; the position one holds oneself must be maintained to match. A profile is kept current by steady attention, and the only effective answer to steady attention is steady attention of one's own.
