That’s also what many other social media would do because it’s easier to ban posting of personal information regardless of where it came from because you can’t trust moderation you outsourced to some third world country to do proper checks.
Example:
Reddit is quite open and pro-free speech, but it is not okay to post someone's personal information or post links to personal information. This includes links to public Facebook pages and screenshots of Facebook pages with the names still legible.
Posting someone's personal information will get you banned. When posting screenshots, be sure to edit out any personally identifiable information to avoid running afoul of this rule.

Dunno if Bsky has something similar but it’s more of a cost optimisation than anything so people are getting pointlessly angry at individual companies rather than the system which has this sort of behaviour as a guaranteed outcome.
