If I set my refrens profile to public, I don't want it to appear in search engine results unless someone clicks on my profile link directly. However, if I set it to private, currently nobody can view it even with the link. I want to make my profile accessible only to those with the link, without it being searchable on search engines for privacy reasons. There should be an option to prevent search engine crawling of refrens profiles. To achieve this, refrens could implement a setting where users can toggle whether they want their profiles to be indexed by search engines. This setting could be found in the privacy or account settings section. By default, profiles would be indexed, but users could choose to opt out if they prefer not to be searchable or indexed by any search engines or bots.
