One response is to avoid/ignore sites like that. Another is to use it but remember that it's all unverified. I've been contacted by alleged past coworkers and accepted their invitations; on the other hand, I haven't given them anything non-public by doing so, so I'm not sure that's a problem. However, people likely to respond to pleas for favors from "friends" they don't know well enough to have valid contact info for should beware.
