WoW can be a friendly place where you can hang out with noobs and hardcores and have fun with friends and chat with cool people. It's also a place where you can risk meeting some very strange people.
Someone I care about recently got herself a genuine stalker from WoW. Imagine the most socially inept person possible finding out that the person he's playing WoW with is a girl...I mean ZOMG!!!1 she must be his soul mate! She was foolish enough to share her personal contact details, they met, things didn't work out and now she can't get rid of the sorry bastard.
Now she gets suicidal e-mails and texts from him and he's stalking her somehow because he knows where she's been and what she's been doing. His behavior indicates that he's either a manipulative psychopath or the most pitiful cry-baby on the planet.
Something to add to that, if a girl doesn't contact you then she's probably not interested. If you're not interesting to her then threatening with suicide will not make you more interesting. It might get you some short term attention but it's hardly something that's a good foundation for a future friendship or relationship.
Just a word of warning, be careful of who you trust, there are some sad losers out there.
