>Is creating a false “Musk” account to spam people with some shitcoin “parody”? Is creating a fake Musk account to post hatefull shit under his name “parody”?

No, and yes. I'm not sure what's difficult to navigate about that? the first might even be commercial speech.

>"What is up with the New Left and this total absence of reason and ethics?"

I don't know? You tell me? Who is the new left? What do they have to do with this conversation at all?

>Actual parody is completely okay and NOT banned (unlike it was on Old Twitter).

There is no category of parody that is "actual parody". There is just parody, and not parody. The examples I provided were all parody that is now again banned... In your example, posting hateful shit as musk is parodic and is banned.
