Whenever someone asks to connect with me on Facebook, LinkedIn or Twitter I try my darnedest to find out who they are really before clicking the accept or follow button. In all three of these networks as of late, I have been using the “Search for this image on Google” option by right-clicking on the profile image in the Chrome browser. 90 percent of the time on Twitter as the spam account factor is 10 times worse than LinkedIn. On Twitter some use celebrity photos, stock photos or other people’s photos as their own profile image. The search image function works fantastically to find where else this picture has been used.
Google’s algorithm for facial characteristics and colors is outstanding.
