Considering how often I see nsfw or nsfl stuff because it wasn’t tagged… no I don’t think so, at least there doesn’t seem to be anything widely adopted on Lemmy.
For images at least it should be possible to create a bot that downloads any uploaded image, runs it through an API like Sightengine, and then automatically removes posts or bans users. Each instance would then of course decide whether to set up such a bot, so there is not going to be any fediverse-wide automod.
I have a Taiwanese friend who is very much anti-CCP, but he does go to china for vacation every now and then.
Yes, you need to be in the right headspace, you cannot expect to vocally or publicly criticize the government and go unpunished. But politics are not everything. China is beautiful in many ways and has many great people. I think it would be a good idea to take the opportunity and make this experience. And afterwards, your opinions on china and the CCP will have a stronger foundation than they do now.
edit: you say you are politically active: is this evident from your social media accounts? That might be problematic.
