Account age, on its own, does not guarantee anything. A two-year profile with no friends, no posts and no graph activity is functionally a fresh account with a misleading registration date. What buyers should actually evaluate is the density of natural activity per month of life — friend additions, photo uploads, comment chains, page follows, link shares. That density is what Meta's trust scoring rewards, and it is what aged-account vendors should be able to demonstrate when asked.
The other dimension is recency. An aged profile with strong activity for the first year and complete silence for the last six months reads to Meta as a dormant account that just woke up — a common bot pattern. Continuous activity, even at low volume, ages cleanly. Discontinuous activity, even at high volume, ages with a question mark over it. The articles below dig into how to read the difference and which vendors get this right consistently.
We benchmark, we publish, we revise when platforms shift. Coverage in this category runs against an active fleet of two hundred accounts purchased anonymously across nine vendors. When a vendor's stock changes — quality up or down — the articles cited below get a revision marker and the change goes into the public diff log.
