It seems that Ad agencies are lifiting photos from Flickr and using them in their campaigns without permission and without model releases from the people appearing in the photos.

In the process of reviewing my images on Photobucket I discovered one photo had mysteriously been renamed and was in a file format that I don't use. I have no idea what this is about. I deleted the image and I am in the process of deleting all other images too.
I will probably continue to use Photobucket but I will expire my images much more quickly and I will start keeping a very close eye on what is being done.
I urge you to do the same. It's a jungle out there. Be careful.
