Doubtful. The only case I am aware of the state banning electoral posters is when a small Strasserite party (The Third Way) called for lynchings of green party supporters and members.
What's really funny about that is that they used a stock photo for this and intentionally flipped it, so that the dude looks like doing the hitler salute. It's just so stupid.
I feel kind of sorry for the people on the photo, assuming they don't support facist. Imagine doing a photo shoot for a stock-photo only to find your face on a poster for nazis.
