Places like Flickr can go fuck themselves because they want 12-character password limits. 12! Some people can barely even remember a 6 string password much less one that’s 12.
Why 12? “SECURITY!” they’d spam. I’ve found it more secure to have a mix of special characters, lowercase/uppercase and numbers than the longer string of a password. Just means you’re going to increase the volume of people having to reset their passwords now and then because you required them to make it 12 characters long.
