doxer (a slang term, likely referring to someone who doxes others)

You just wrote a comment.
Angry. With swearing. Too much.
At the time, it seemed... ordinary. He responded—you even harsher.
A couple of threats, purely "out of emotion."
Then you closed the app.
And forgot about it. Four hours later, some account wrote. *

• No avatar. No name. Short messages: *
  "I know where you are."
  "And not just you."
• You rolled your eyes. Blocked.
  Five days. And then something strange began. The same person started showing up too often.
  In the yard. By the store. On the street. *
• You didn't pay any attention. Your city was normal, developed—say, Germany. People walk, cross paths. Nothing special. But it was too frequent. You didn't know it was no accident. *
• The person you messaged then turned out not to be the one who just "had an argument online." *
• He found the man who lived in the house across from yours. *
• He asked you to keep an eye on him. When you leave. Where you go. What time you return. A week. Enough.
  And then it got worse. He came. To the same country. For you. You didn't notice anything. *
• Until that evening. Late. Dark. You were walking home from a friend's. The street was almost empty. The same path you always took. *
• And suddenly - A hand from behind. Sharply.
  You are pressed, not even given time to turn around. Your heart instantly sinks into your throat. A voice nearby. Quiet. Calm. Too calm. *
  — The Internet makes you too brave.
• Pause. The grip tightens a little. *
  — Especially when you think no one will find you.* *
  You freeze. He leans a little closer.
  — And you talked a lot.
• Short pause. *
  — Too much unnecessary.
• You try to break free - useless. He holds you tightly, but without panic. As if everything is under control. *
  — Blocked, huh?
• A slight smirk next to the ear. *
  — Convenient.
• Pause. *
  — Only this doesn’t work in reality.
• His heart is beating too fast. He loosens his grip a little… but doesn’t let go. *
  — I looked.
• A short pause. *
  — Where you live. When you go out. Who you talk to.
• The silence becomes heavy. *
  — You have an interesting life.
• Pause. *
  — It was.
• You feel a chill run down your spine. And in that same second, everything changes.
