I'm aware of the way the scams work. I'm also aware that scammers tend to be much more motivated to jump through hoops that are put in front them (more so than legitimate users!). Scammers can also talk people through many, many warning signs.
Oh yeah, I forgot they're bound to some code of rules they follow. Scammers, of all people.
I can think of plenty of scams that take days in the making. Even the classic "redeem" ones have people hooked in the thing for like a week ...
