A few observations, based on a family member experimenting with DeepSeek. I'm pretty sure it was running locally. I'm not sure if it was built from source. The censorship seemed to be based on keywords, applied the input prompt and the output text. If asked about events in 1990, then asked about events in the previous year DeepSeek would start generating tokens about events in 1989. Eventually it would hit the word "…
If this family member is experimenting with DeepSeek locally, they are an extremely unusual person and have spent upwards of $10,000 if not $200,000. [0]

It was not running locally. This is classic bolt-on censorship behavior. OpenAI does this if you ask certain questions too.
