Intercom randomly generates names for unknown users.
I see that this was raised 4 years ago however the issue is still unresolved: https://community.intercom.com/conversations-9/why-does-intercom-randomly-generate-names-for-anonymous-leads-192
Qualifying leads is not a solution if the conversation is not on Intercom Messenger but, for example, on Whatsapp.
There needs to be an option to disable this feature, as mentioned in the thread above there are too many confusing colors in the random names such as “Amber” or “Violet” which are commonly used as names as well.
