Similar to when you build trust on ebay or another "selling platform", where accounts with zero or few recommendations/interactions are normally seen more critical than established traders/accounts with hundred or thousands of recommendations.
And no sane person would throw away an account with thousands of good recommendations, just to rugpull someone for a few hundred bucks.
Same reason, why the darkmarkets normally establish trust over a longer period of time, till they rugpull, because then they get more out of it.
Or why accounts with many followers which existed for many years are worth something, because it takes time to build up something like that.
