I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

Glückwunsch! Das war auch der Teil des gesamten Verfahrens, vor dem ich am meisten gestresst war (mehr als beim Vorsingen 😆). Zum Glück hatte ich aber einen sehr netten Amtsarzt.

Was TikTok blocking certain political posts last week?

We investigated & found no systematic evidence of political censorship on TT post-restructuring at this point. A server outage better explains the data. But the story isn't over, and platforms need to provide the public more transparency.
Last week the story was that TikTok censored anti-Trump/ICE/Pretti videos after the U.S. ownership change. We investigated with a large set of US TikTok data and found some interesting results, short thread...
