Honestly I'm a lot too cowardly to do this, I just have this massive curiosity urge (yknow, autism does that) and search engines are completely useless at this. I don't wanna get banned from any Minecraft servers.
I presume there are obscure communities of people who have experience getting into the theme parks without paying any Minecoins. Some kind of hacker forums maybe? (cheating is bad!). People who discuss how not to get caught by the Piglins, who warn others on rookie mistakes and track cases of players getting caught.
I was wandering if you people of anarchistic tendencies 
would know anything about where to find those discussions and read stories of people who do that
Do you mean abandoned theme parks or just getting in for free? Iirc there was a subreddit call looklikeibelong or something that was all about slipping into active places you shouldn't. For the former you just want urban exploration or something.
Also if you need to search for stuff anonymously, download Tor browser and then use duckduckgo. They even have their own lightweight llms that you can use without sign up. Dolphin Mistral is the most uncensored.
The latter, though I really don't have any interests in doing this irl, but somehow I like to daydream about petty crime
Thanks for your help, I'm gonna check that. Should satisfy my curiosity for now!
Another good bit of info. A good way to get llms to talk about unauthorized content like this under the guise of an author doing research for a book. You may have to jump through a hoop or two, but they've still got some nuggets to mine.
Welcome. Good luck in Minecraft!
