I got such good answers here yesterday I thought I'd try another one that's been bothering me and causing me problems.  
       When researching  girl I always google image search her pics looking for stolen pics, fakes etc, like I'm sure most everyone does. Sometimes you run across an issue, usually the girl used a pic that leads to RL info she most likely doesn't want known. I used to routinely inform them of the issue and move on.    
       I would say about 40% of the time I don't hear anything, about 20% of the time I get a courteous "thank you, I didn't know". But the other 40% take time out of their busy schedule to give me attitude about it. "I didn't ask for your help" "don't try to tell me how to run my biz" etc.
       Recently this really bit me when one  of these girls got the idea I was stalking her and has been going behind my back telling the locals not to interact with me in anyway.  
      Which brings me to the real point of this thread.  Today, while researching a new girl I discovered her real identity as well as the fact she studied "criminal Justice" after high school Now what?
A. forget about it
B. warn her
c. warn everyone publicly
d. warn friends  quietly
e. other (elaborate)  

A. Mind your own business.  

that being said, it would give me a pause if I was thinking of booking with her.  

I'd just drop it, and don't bother trying to see her.  If she's that careless about her identity, it may come back to bite her in the ass, or you, and there is nothing you can do about that.

I have 2 online friends/ buddies whatever you want to call them that are actively wanting to see this girl, you don't think I should warn them she's lax on security and studied to be a cop?

I was just concerned  for the bros who don't look as close. Her pics are also bout 10 years and 20 lbs out of date from her facebook.  

and now you are "concerned" with the guys who wouldn't look too close...

my plan was to just not bother anymore, the saying " no good deed goes unpunished" comes to mind.
But this latest one, with the LE implications, makes me question that.  

And I am glad you are someone who would not take offense to it if pointed in the right manner, but a lot of them do.

I had already alerted the guys who were thinking of seeing her of what I found so they could decide what to do. They decided to cancel, due to the new/ current pics not being anywhere near as appealing as the old ones and I guess she wasn't a happy camper about that.  
I decided to warn her as well, she was thankful and changed the pic.
All's well that ends well I guess
Thanks for the help folks  

just for the record just because she studied criminal justice doesn't mean anything.  I majored in Criminal Justice in college along with a bunch of others who became counselors, lawyers, etc.  I guess I could have gone the cop route but since I'm not excessively short with a cheesy mustache and lift weights incessantly to make up for it I decided to go another direction.

she suggested I search her criminal record if I was concerned she was a cop, I did,with her record that's unlikely at best lol.
The whole thing seemed weird, she claimed to be around for 8 years yet had no reviews for example. Taken as whole, not worth it.  

I've had guys email me before telling me that my ads are too wordy, I should tour Frog Balls, Arkansas, I need photos of me wearing x, etc. Stuff like that can come off as a little condescending, but if someone were to tell me privately that there's something that could potentially cause me problems in my personal life, I'd definitely appreciate it.  

I asked this girl the question, "What did you think when you got my email? Did you think I was going to try the use the info in some way?" She said "no, why would I think that? I was happy you pointed it out and changed it immediately" I explained my experiences and she said the same thing, "are they idiots?"
