I made a post with the title something like:

"AI bubble will pop" is the new "This year is the Linux year". Changing my mind.

My intention was to start a discussion about people saying AI bubble will pop but it never happens.

It was meant to be provoking to motivate people to try to argue.

The thing is the post completely disappeared from my profile, I can't even see it anymore? Is it normal?

I don't think this is reason enough to permanently ban me. I didn't even get a warning, mute or something.
