I also do a search by image on your profile picture on social networking sites such as LinkedIn and Twitter. It is naive to assume everyone is who they claim. What appears to be attractive young woman friends with colleagues on LinkedIn might lure hackers to information.

Conclusion

Surprisingly often, I find potential contacts have been stealing their profile photos from Facebook. I found the same photo used to advertise escort services. Scammers often use the photos of long-forgotten film actors and writers as well.
