What kind of credit rating do you say is safe? Are people with address and identity verified usually genuine?
I look at a lot of different things. Crediting rates are a good way to weed out the quick scammers, but you still need to do your homework. I would look at a lot of things, like interest rates, if they have a forum name what kind of post and time have they spent on the forum. Look for secured loans with stocks that back up the price for the loan. Just do research, and you should be fine, there isn't a defined formula that will weed out complete scammers.
