No, not at all. You just have to look at a few till you find decent people and it's what you're looking for. As long as you don't give out any personal information? You'll be fine. You'll go through a few to find what you want.
The thing to keep in mind when conversing with ANYONE on the internet is to be cautious and do not divulge too much information . .. Especially of a personal nature. Never be afraid of using common sense
