Part of my job is analyzing web pages and websites for a search provider.
I am continually surprised by the number of people on this forum who use Photobucket and seem to not realize how much of their information is available to someone who randomly clicks a photo that they post, I have seen full names, addresses, children's photos, etc.
Even if you set your albums as private, often other parts of your account are not private The most disturbing thing I see is people using their real name on their account. It often shows up plain as day when anyone clicks an album..
I don't think anyone here has evil motives but it does pay to be careful. There have been instances on this forum where there is a spat and a user has escalated it off the forum. Double and triple check when you post a photo to be sure that you aren't revealing information that you would prefer to keep private.
