As I explained in the other guide, somebody can only have you as an halfvalue Friend if you also have them as an halfvalue Friend, so you know exactly who those people are. What you don't know is who has you as an halfvalue Favorite. It would be great if halfvalue provided an official way of finding out, so that you could check whether any of those customers are of interest to you. Well, halfvalue doesn't provide a way but you can find out using 'Google' or 'Google UK'. The method given will show your halfvalue Friends as well as those who just have you as favorite - and will also show friends and favorites of your namesakes - but I cannot find a better method than this.

First, go to your chosen Google site and click on the "Advanced search". In the top box enter your name (replacing any hyphens with spaces - hyphens have a special meaning in Google) and the following words

profile friends favorites latest activity

Do not use quotation marks. If you wish, you may change the results box to the right. The value showing is 10 but you may change it to 20, 30, 50 or 100.

Further down the page you will see a "Domain" option. Leave the "Only" option as it is and enter amazon.com in the other box. Now hit the enter / return key.

You should now be offered the first in a series of Google pages showing those people who have listed you (or your namesakes) as an halfvalue Friend or halfvalue Favorite. Check each in turn to see if you (rather than a namesake) are on their list, ignoring those you already know to be friends. If you have too many namesakes, you may edit your halfvalue name to include your middle name or initial if you have one but didn't use it originally. Note that this new name may take a few days to work its way through halfvalue so don't try the new name for another week or so.
