How some people use flickr...

It has come to my attention that some people use flickr as the primary repository for their pictures.  Then, for some reason or another (warranted or unwarranted) flickr closes their account and they apparently lose access to all of their photos.  And then they blog about how flickr closed their account and they have no other copies of these photos. People use flickr to store their only copies of a photo? Why would you do this?   Come on people, get some self-reliance...
