Posting on social media anonymously without getting shadowbanned

I want to start posting on twitter but with most anonimity possible. I am afraid that twitter my flag my acc for suspicious behavior. This happend to me once when I was using my old VM system and all my comments were dumped into “spam” section. I dont know the actual reason - whether this was my VPN (however twitter does not forbid VPN) or some kind of fingerpriting? Before i start my trial-and-error run I would like to hear and external opinion about my idea and VM setup to: 1. Fresh Ubuntu system 2. NAT Adapter instead of bridge 3. No host integration (like drag-and-drop) and no guest additions 4. Firefox with privacy extenions / Brave with profiles 5. always same system language as my VPN 6. Something to prevent getting fingerprinted by canvas What else I have to do to start posting anonymously without risk of being flagged/shadowbanned? Any tips are welcome. And to be clear: i am not going to post anything bad. I wont probably break ToS. Just want to make sure no one who doesnt like me wont find me.
