I was doing a dog related google search and not surprisingly some links to this forum popped up. I was surprised though to see a couple of members full name (first and last) appear next to their user name on the google page. These were links to the members' profiles. I did some random google searching and came to the conclusion that the names are whatever the member intentionally entered into their profile.
But the only place that I can see where these names appear on the members' profiles is in the "friends" area. If one doesn't have any friends listed, I cannot see any other place in their profile where their full name (or whatever they entered) is displayed, yet they still show up on a google search.
I guess my point is that it's possible some members may think some information (such as a last name) isn't public because it's not showing up on their profiles, when in fact it is being displayed on google. I hope I'm not just being dumb and missing something obvious, but feel free to let me know if I am.
