Tons. This on is from Oct 30 in The Nation:

The German state’s show of support has led to an outright banning of most pro-Palestine protests. [...]

The reasons for the bans seemed unambiguous: German police said that there was an “imminent danger” that the assemblies will result in “inciting, anti-Semitic slogans,” as well as “glorification of violence.”

Preemptively. Because antisemitism and "glorification of violence" might occur. And by antisemitism they mean things like this:

On October 13, Berlin police declared uttering the slogan “From the river to the sea, Palestine will be free” forbidden and indictable. That same day, Berlin’s education senator, Katharina Günther-Wünsch, sent a letter to all Berlin school principals offering them the option to ban students from wearing “pro-Palestinian symbols such as the keffiyeh.” “Any act or expression of opinion that can be understood as advocacy or approval of the attacks against Israel,” she wrote, “constitutes a threat to school peace and is prohibited.”
