What actually triggers X shadow limits these days?

Between rapid posting, links, or certain keywords, it’s unclear what flags accounts. Anyone figured out patterns that consistently reduce reach?

Posting or commenting too fast, too frequently, or repeating the same comments over and over are some of the top reasons accounts get shadow limited on X. This is especially true for new accounts that haven’t been properly warmed up or built enough trust yet. In those cases, X is very likely to treat the account as bot-like behavior and flag it accordingly.
