SeptemberMorn is right. You can't know anyone you meet on the Internet. Even in real life, you can't. People can lie, and some are very good at it. On the Internet, it's even easier to lie. Just be careful, and do the best you can. Don't beat yourself up if someone betrays your trust. Maybe you trusted too easily or believed something you shouldn't have, but it's the person who broke your trust who is wrong. Just because you walk down a dark alley, which we all know isn't smart, doesn't mean somebody has the right to harm you. Blame the one who intentionally causes harm, not the one who made a mistake trusting.
