This is my profile on Stack Overflow. As I remember recently I had two questions. One about PlayN (still there) and one about sbt-osgi (how can I set a target platform). There were somebody who downvoted both recently (I just guess it is a single person, not two individual visitors of the question within 2 minutes.) Although it seems the question about sbt-osgi is gone.
Do you have an idea what happen to it? (I do not remember deleting it, cannot see it in the recently deleted questions section either.) I have deleted one of my answers recently for a duplicate question, I was unsatisfied with my answer. Could it be related?
