My gf got an offer from a porn site. (NSFW description)

So, my GF just got an offer to join a web cam site, the type where you watch girls go solo, so, my conflict is this, do i let her make the cash, but risk her going into the world of porn? Or do i simply tell her i dont feel well about it? normally this wouldent be so worrying, but we REALLY need the cash :/ ( also, disclamer, we do post in GW, GWplus, and Trees gone wild)
