"Victim", as understood by most people, implies that someone did something wrong to them. There's nothing wrong with seeing someone's profile online, so your analogy doesn't apply.
Thought exercise: Am I being a "victim" of you, because you posted a comment disagreeing with me?
There is no crime here is true. I really hope that's exactly what you mean.
However this person that is unstable or at least very aggressive and is clearly trying to track someone. I really hope you don't mean that because someone is publicly available that it is ok to do what you want to them.
IE "asking for it" because a person was around to commit a crime against so its their fault for not staying behind locked doors with a shotgun their whole life.
You are very close to simply stating that having an online profile makes it ok to do things to someone because you have dictated they should not have one if they don't want to be a victim of a crime in the future. You are also sort of imposing your view on everyone in the world that social media is not a necessary part of life nowadays. (that is a different debate)
