Instead of them being visible to everyone, make their visibility scale with distance. When you get shot at, you only see a close to you part of the trail, you know roughly from where, but not the exact position. This also makes it less of a "Im here, please shoot me" for unrelated players.

tldr: Instead of it being a message to the whole map, let it be only to the person getting shot at.
