It can invite the other person to view the sender without requiring a full opening message. Some services use it as a free action before paid messaging.
A favourite may be visible or private
On some platforms the saved person receives a notification; on others it is only a bookmark. The icon alone does not reveal the product rule.
Direct messages carry more information
A short message tied to one profile detail gives the recipient more reason to respond than a generic signal, although it may require credits or premium access.
Common questions
Read this quietly.
Does a wink mean someone wants to meet?+
It only signals initial interest.
Can people see when they are favourited?+
It depends on the service.
Why use a like instead of a message?+
It is quicker and may be available without paid messaging.
You favourite a profile as a private bookmark on one service; on another, the same action may notify its owner. The icon alone cannot tell you which model applies.
Wording you can adapt
Check the help text before assuming a saved favourite is private or that a like opens free messaging.
What this clears up
Treat lightweight signals as interest, not an agreed introduction. A notification can prompt a conversation, but it does not say the recipient is available or wants the same arrangement.
