The sophistication of attacks increases in relation to expected payout. My aunt fell "victim" to one of these scams after winning the lottery. It started off with the standard spam, then when she responded the scammer became more personal, learned about her, and after the initial "investment" began an online romantic relationship with her.
After the family learned that she had given $250k to this guy, we stepped in and put a stop to it. She was embarrassed, and ashamed... and kept talking to him. We found out later that she had given him more money, after their "relationship" had continued for a number of months.
FTA, unsophisticated attacks select for unsophisticated targets. As the likelihood of a payday from a given target increases, so too does the sophistication until an equilibrium is reached and increased effort no longer yields increased rewards.
