There are two answers to your question.
- No, because you need to follow their will if the profile owner wants a request to down their VCF.
- Yes, this is why the profile owner thinks it is acceptable for their contact to be freely downloaded and sets the VCF request off.
As a visitor, you may be concerned about providing your email address, but how will the owner contact you? A credible business networking event in which both persons have the information they are permitted to communicate back after the connection, and one-way communication is like viewing a painting in which there is no interaction.
We allow the profile owner to choose whether or not their VCF will be on request or freely accessible. They'll also select what is permitted in their VCF for download if they are a Pro Account user.
