Much to think about.
I guess one way to put it is, unless you are willing to have this member show up to your house and for you to be willing to serve tea to him/her/them, don't tell them any more or your location than maybe a state or vague region.
Also given, as great as it may be to tell people about your vacation, sometimes you shouldn't let your members know details of where you're going in the immediate future, or specific details of your hotel. For example I had a model-friend very enthusiastically tweet to all her followers that she was at a hotel near a theme park with a very specific (and until very soon in the near future, unique) theme.
I have another (much newer) model-friend who is driving me up the wall with how open she is about where she lives: she's mentioned city, favorite restaurant being very close to her apartment, and her favorite store being across the street, and it turning out that store is at only one mall in the entire city she lives in. And every time I'm like, "please stop doing that, I really don't want some psycho stalking and maybe hurting you".
Mentioning, by name specifically, where you've been and had a great time in your city is a start for someone to find you. If you've had a great time there, you're likely to go back
It doesn't get mentioned much as it's less likely to happen and probably far less of a threat due to power dynamics involved; but members need to be careful divulging details in chat. To know that one guy drops so much money and owns a very specific store type in this region, means he's putting himself at risk of violence out of potential profit or jealousy.
And of course even far rarer, I've never heard of it happening IRL, is the prospect of a model stalking a member.
Only a small handful of models know where I live; far fewer know my real name; so far four have seen my face on cam or pictures; and only one has my home address (and I was very hesitant about that for a very long time).
I've met a total of three cam-models (by accident) in real life, and all three were while working for a Horror convention in town, thought they looked familiar somehow but went back to work and only later found out online who their online personas were.
