Strange things

So why do we get so much spam, maby it’s because you use yahoo email or maby it’s because you are just to damn curious or trusting.So if I request you send me your bank account number so I can put two grand in there for you just because you deserve it,would you do it.Not.So when something is offered that seems to good to be true,why do people go for it. my best guess is one they are greedy,two they just want a friend,three they trust people.you decide.
