Now that you point this out, I realize that it’s so true. Of course a cluster B person like Anna would fall for a scam, accidentally or not-so-accidentally (i.e., setting themself up to get attention and sympathy), and then take absolutely no responsibility for their actions and blame it entirely on the scammer(s). They never learn from their mistakes either since the capacity for self-awareness, genuine insight (as opposed to fake uwu Daddy God has taught me so much through my hardships “insight”), and growth is so stunted. So they keep falling for scams.Some personality-disordered people specifically look for scams that are seen as "not the person's fault" when they fall for them, and blame monetary losses on them.
It’s hard to tell whether this was an intentional ploy for sympathy or she actually is that dumb, but like you said, time may give us a clearer picture.
