if police want to find you they will. so many cases of high profile people running online crime orgs getting busted.
even vpn and protonmail is not safe. consider a news article from last month -- protonmail cooperated with spain police. vendor provided authorities with the recovery email of one of their users. it ended up being the users personal icloud. police made quick work of what to do next to arrest the person for their investigation.
do deep dive in opsec will help point you in what NOT to do. especially reading about people getting busted. e.g., do not put recovery email/phone on accounts you're using to break local laws that point directly to you lol. i would probably start researching how other Malaysians have been caught for similar charges.
for starters get a vpn. just find a leaked account online. sure you can buy with crypto. but authorities may ask the vendor "hey what's the crypto address of this person". then run a blockchain investigation to the funds and trace it back to your coinbase. then they ask coinbase "hey who is this account". and it's game over for you: your identity has been compromised.
so many big people busted. people who think they are really smart in security and hiding their footprints. ross ulbricht was busted in a library with his personal laptop lol. but porn reupload likely not that high on the list of priorities for Malaysian police. compared to say running crypto tumbler or drug market. either way this is one of those things where you're walking a tight rope with your freedom being in malaysia.
to answer your questions -- offshore hosting protects you against dmca + copyrights. cloudflare doesn't really obfuscate much past there surface. it's an illusion.
there are free tools online to de-obfuscate instantly. when a copyright holder sends dmca they will likely send it to cloudflare who will boot you off the platform. hide origin site? everything is so easily looked up. just use registrar that plays nice, use fake name, vpn, fake email, and billing that is not tied to you. sounds like a lot of hoops to jump through doesn't it?
