I have been a buyer since February 2009. That was my first account with Etsy. I chose not to disclose my favorites for many reasons. However, you can be sure that 90% of the time I went back and purchased those items. I was not interested in participating in anyway - and was not interested in other people looking at my favorites.
Having a shop is quite different. Now I do share, belong to Teams, include shops in my circle, etc., and have even purchased a few items - but I still do most of my shopping through my other account with Etsy.
So, you see, it may not be that bad to have "secret admirers". They may represent prospective buyers.
Take care.
