displaying the actor or their notes will have some special effects
attached in some clients.

This is a shallow copy: property arrays are copied, but nested objects and URLs are shared with this instance. Dereferencing accessors can cache fetched objects in the instance whose accessor is called. Hydrating a shared nested object through the clone can affect the original as well, and can change JSON-LD output when either is embedded in another object. Hydrating a top-level property of the clone does not update this instance's property.
To resolve properties without sharing nested objects, serialize and re-parse the instance before hydration rather than using this method. See the vocabulary manual for details, including how cached JSON-LD affects serialization.
A clone never inherits a signed JSON-LD representation retained by
signObject(): the clone may differ from the document that the proof
covers, so embedding the original secured JSON in a parent document
would be wrong. Sign the clone again if it has to be embedded as a
secured child.
getAlias(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<Application | Group | Organization | Person | Service | null>The aliases (alsoKnownAs) property is used to specify alternative names
or aliases for an entity. It can be used to provide additional identifiers
or labels for an entity, which can be useful in scenarios where an entity
may have multiple names or aliases.

It serves as equivalent to
the publicKeys property, but is used for FEP-521a compliance.
getAssertionMethods(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): AsyncIterable<Multikey>Represents this actor's public keys.

featured at the top of people's profiles, is implemented using an extra
property featured on the actor object that points to a Collection
of objects.
getFeaturedCollections(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<Collection | null>A collection of FeaturedCollections created by this actor.

at people's profiles, is implemented using an extra property featuredTags
on the actor object that points to a Collection of Hashtag
objects specifically.
getFollowers(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<Collection | null>This is a list of everyone who has sent a Follow activity
for the actor, added as a
side effect.
This is where one would find a list of all the actors that are following
the actor. The followers collection MUST be either
an OrderedCollection or a Collection and MAY be filtered on
privileges of an authenticated user or as appropriate when no authentication
is given.
getFollowing(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<Collection | null>This is a list of everybody that the actor has followed, added as a

or a Collection and MAY be filtered on privileges of
an authenticated user or as appropriate when no authentication is given.

The server SHOULD filter content according to the requester's permission. In general, the owner of an inbox is likely to be able to access all of their inbox contents. Depending on access control, some other content may be public, whereas other content may require authentication for non-owner users, if they can access the inbox at all.
The server MUST perform de-duplication of activities returned by the inbox.
Duplication can occur if an activity is addressed both to an actor's
followers, and a specific actor who also follows the recipient actor,
and the server has failed to de-duplicate the recipients list.
Such deduplication MUST be performed by comparing the id of the activities
and dropping any activities already seen.
getLiked(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<Collection | null>This is a list of every object from all of the actor's Like
activities, added as a
side effect.
The liked collection MUST be either an OrderedCollection or
a Collection and MAY be filtered on privileges of an authenticated
user or as appropriate when no authentication is given.

If a user submits a request without Authorization the server should respond with all of the Public posts. This could potentially be all relevant objects published by the user, though the number of available items is left to the discretion of those implementing and deploying the server.
getPublicKey(options?: { documentLoader?: DocumentLoader; contextLoader?: DocumentLoader; suppressError?: boolean; tracerProvider?: TracerProvider; crossOrigin?: "ignore" | "throw" | "trust"; gateways?: readonly (string | URL)[]; verifyPortableObject?: PortableObjectVerifier; inheritPortableObjectVerifier?: boolean; }): Promise<CryptographicKey | null>A public part of the key pair owned by this actor.
