Does stalking happen in Second Life - Unfortunately it does.
Does it cross into real life - Unfortunately it can and has done.
Stalkers come in both genders, male and female, which is worse? Neither, in my opinion.
Your Second-Life profile can be a window to you. Your profile can also be used to harass you by other members of the SL Community. I am not trying to frighten you, I am merely pointing out that it can happen, and has.
I am not trying to scare you, but the sooner you realise that you are your own worst enemy in virtual worlds, the sooner you can protect yourself.
