Shady characters seem to show up pretty much anywhere something "popular" happens. Perhaps they are especially drawn to ventures where there is an "opportunity" of sorts. And so, they come here... as they have come to pretty much any form of "opportunity" for as long as I can remember.

Their central thought — before they even start — seems to be "How can I exploit this without having to do the work?" I realize that may be an inevitable mindset of the human condition, but it still annoys me.
