German digital campaigning is so weird. There's a fraction over three weeks to the election, and the biggest parties are doing *nothing* with digital ads. E.g. SPD and CDU are spending around 1/20th of what Labour and the Tories were spending in the UK with three weeks to go last summer.

Ok after a couple more tries it seems that the server was indeed just busy when I asked about Chinese history. Still pretty powerful to see how responses on e.g. Taiwan are being typed out before your eyes and then magically vanish because of 'scope'

At least now I know that Mao was a pretty swell guy

Who could have guessed that DeepSeek is not the best place for learning about Taiwan's history and political leaders... Surprising though that even Chinese history brought up a filter unless specifically prompted to give me something uncontroversial.
