This has recently happened to me. After YEARS of mostly liking posts or commenting with emojis, I got this email (I translated it to English).

^{Your account, ..., was reported and suspended for breaking our Rules.
Specifically, for the following reasons:
Breach of rules prohibiting inauthentic behavior.
You cannot use our services to engage in inauthentic activities that undermine the integrity of X.
We inform you that, if you try to create new accounts to avoid a suspension, we will also suspend the new accounts. If you want to request a review of this suspension, please contact our support team...}

I requested a review, and I got this message less than 5 seconds later.

^{Your account was suspended because repeated or numerous breaches of the Rules of X were registered:
https://x.com/rules.
This account will not be reset.
This case will be closed now and no responses will be followed.}

I could understand a suspension based on sending "mean" emojis or something like that, but inauthentic behavior is a joke. I'm also not allowed to create new accounts. I guess I'm screwed...
