Streamers and influencers will often make a living off of their name and face. If they are openly criticizing and threatening the country they intend to move to, then maybe they shouldn't be allowed over there. Imagine someone like that hiding their posts, entering the country, and then unhiding them immediately after.

Nah, if someone makes a living off of their economic or political beliefs then they should have to choose their country based on those beliefs. Some random Joe with zero following should be able to keep their profile to themselves though I think.
