You could use a VPN, yes. But in case your PC or smartphone gets seized by the government, you are in trouble. Other than that, it is very difficult for the government to track VPN usage. You would need to be under investigation and the government would request your browsing history to your Internet Provider. I think Tor would be the safe option, but I'm not sure.

The main app stores hide VPN apps from their catalog if your IP is from Brazil.

But would you go for the trouble of using VPN if most people you followed are not there anymore? Most will not. People are trying Threads (ew) and Bluesky (lesser ew) and Mastodon.

The biggest issue normies found was the loss of community in a known platform that has been used for more than a decade.
