I suspect that either (1) someone misclicked or (2) someone unscrupulous took a dislike to something else you wrote and decided to downvotes lots of your comments. If it’s just this one, it’s probably #1. If you suddenly lost a lot of karma, it’s probably #2. That sort of bulk-downvoting is not supposed to be a thing that happens here, but sometimes people do it (in my experience, usually for political reasons; they’ve decided that some other person is The Enemy and must be punished and their voice suppressed); if you have good reason to suspect it’s happened, you might consider contacting the site admins.
[EDITED to add: I (weak-)upvoted seed’s answer even though I do not live in Berlin, because I can think of no reason why it should have been downvoted.]
What the heck did I do wrong, why are you downvoting me, guys?
