Robert Simpson well sort of... I personally am not worried.. I gave up trying to hide when on the internet years ago - that said - its more about information control. Willingly putting yourself on a list is very different than being scraped for a list etc...as stated...

Its just one of these issues that in the end Google will probably get blamed for sadly... enabling great features like this always leads to some jerk abusing them and then all of us paying for it...just a sad state of the reality of the net ...

Shared circles would solve this in many ways - I would keep the lists etc internal to G+ - I could share my photo circle and people could add people from that circle etc... vs. having the need to maintain external lists of this information.

As I can tell - anyone can contact me via my profile page that then emails me to my gmail acct...so unless you disable this - anyone can contact anyone - but anyone cannot have a full excel sheet of targeted contact info.... In the end the list is hours and hours of work for a marketer to put together...

Do not take it wrong - I have no issues with it... I want to be on every photographer list out there..and feel free to follow me and my work - that said - I have been thinking about these features more lately in relation to overall internet security etc... I run a site called www.coptalk.info - we get questions all the time related to internet social sites and staying safe etc... it's just an interesting problem overall and thus a topic to discuss more in depth....
