But I'm not sure what you're talking about are contexts where people think they're doing a banned or taboo activity.

Looking up a YouTube video on banned TED talks and etc sounds like a safe, banal activity one does from home. You can tell your coworkers, your friends, the police, and nobody will care. I would suggest that for the US, something taboo would be like talking about racial supremacy and eugenics.

But due to free speech rights and history, I'm not sure the US has something similar to a political or national event people can't talk about. I would also say cultural retaliation is different from government retaliation.
