All of us on here at one time or another have been rejected. As disheartening as that is, it is a part of life and you can either let it defeat you or get back up and keep on keeping on like a bird that flew to paraphrase the great Robert Zimmerman. :)
The point is that our picture and info might be out there to begin with. If there is a way to do it, CM should prevent our pictures from getting out from this site. If it's true that pics from our scrap book are protected, then our profile pics should be also.
Can't offer any specific insight there. However, a few observations:
If you look at my profile, there are pictures of me with friends, there are "mug shots" and there are pictures I took of other things. At the risk of sounding more eccentric than I really am, I HATE having my picture taken!!!.......... Trust me, it didn't hurt a bit, and the upside has been, people actually like my pictures. So if you're faceless right now, think about what we're saying. It could be that we want to meet you, but you're holding us at arms-length by refusing (however politely) to share a photo. Say "Cheese" !!
You would be surprised about how much information you can find out about people just from what is posted on CM. Not trying to freak anyone out, but if you are not from a major city, you have an uncommon name or uncommon spelling, it's not to hard to find you on-line. I should say that I am NOT a cyber-stalker. I find it fascinating what is available on the internet. I've been able to find quite private information about extended family and friends and am uncomfortable with the fact that my 90yo grandmother (who lives alone) has her full home address available on the internet.
There was a similar thread in the Woman's forums a while back and I googled some of the women there just so they knew what was out there. While women are typically more careful about these things, but some people will have pics posted in a shirt or hat of the company where they work or somewhere they volunteer. With that info, I can search for you on LinkedIn which then gives me your last name. Now I can google your first name, last name, age (or year your were born) and find out where you live, family information, your facebook or instagram page and more all for free! You can also drag a picture into the google search bar and see if that picture shows up other places on the internet. I used to use the same profile pic across multiple sites and now I use one personal, one professional pic. Depending on your profession, it is important to have information out there about yourself, but also depending on your profession, it's important NOT to have information about there as well. For me, I need to be out there, but not totally out there.
