Most likely multiple people flagged multiple comments of yours in the past month or so (as best I recall I believe I've flagged at least one of your comments (not more than three), can't quite recall which) for being "not HN" (ie overly edgy, somewhat combative, overly stylising US | China conflict, snark, etc) .. see the HN guidelines.

I've had a chuckle or two at your comments, but HN was founded with a preference for more thoughtful comments, fewer jokes and snark, etc.

FWiW I'm currently rate limited albeit with enhanced flag powers (I swat a lot of spambot crud) .. go figure <shrug>.

After enough flags you can land in autoflagging and shadowbanning .. unless you email dang and the modteam ( [email protected] ) and reset.
