Accounts which have been active for a long time, and are therefore higher rank, are more likely to have built up a good reputation than a newbie account. Conversely, simply being active for a long time doesn't automatically mean more trustworthy. So although highly trusted accounts are more likely to be highly ranked, higher ranks aren't inherently more trustworthy.
The higher one's rank the bigger the opportunity to burn your account and disappear will be. I've seen many a hint that a decent number of established members don't have a pot to piss in.
No one should be under any illusion that if something landed in a long standing member's lap the temptation to exploit it will be strong and it may only not have happened because the chance hasn't arrived yet. There are enough old schoolers here who wound up screwing people.
We'll never know whether it was a long con or spontaneous but the higher up you go the more is dangled in front of you if you've placed yourself in the right circles.
There've been people I've grown up with who turned around and fucked me for piffling advantage after knowing them for decades. On the internet I'd times that possibility by a few million no matter how carefully crafted someone's rep is.
