Does she really know the guy?Like did she actually see who he is or had a conversation with him on the phone or something ? (not saying she should do that) but if not then tell her that he could be an old guy who has nothing to do instead of just sitting on the comp and doing that kind of stuff with young girls like your friend , because seriously..thats just sick. If she tells you that she saw a pic of him...that doesnt change it because either he could get any pic of a cute hot guy and say that it is him , so i guess you need to tell your friend about what if...that or that...etc , iam sure she will start to think about it and maybe stop ?
Also i think this should go to the Advice forum , iam sure a Mod would move this later on. sweatdrop She could tell him to take a pic of himself doing something really specific... you know, like standing on his head, reading Harry Potter, and eating a pie while wearing plaid pajamas. ^____~ If he does it, it either means that he's not faking his identity, or that he's really good with Photoshop.
...but I don't really have advice for the actual cybering problem, because I'm, uuh... not really against it. XD; I think cybering is kinda silly, (though not as silly as phone sex...) but not really all that bad.
