I think it helps to be selective. Of course we all run into nasty people here and there but in general they wouldn’t be your friends. So when you state you have friends like that, then it’s concerning why you build friendships with these folks? Not everyone should be your friend.

You don’t know who people are online. If it’s anonymous, there’s no way to know who you are even talking to. Might be completely different person than you think. Could even be a teenager for all you know. Be careful who you are talking to online

Yea you can protect yourself from predators by not trusting everyone you meet and not open up to strangers until you know them well
