At some level, yes, but LinkedIn hasn't been particularly welcoming of those sorts of employees in the past (presumably because it makes some of their other customers squeamish).

Plus, there's the issue of whether people are working in the industry willingly (likely not), whether they are subject to violence (probably), and how much of the money you paid they will actually get to keep (very little). (It has been argued that legalization and regulation would solve these issues, but I have no idea if that's true or not.)
