Disadvantages of modern image hosting

Hello, dear Habralyudi!
Now there are a lot of repositories in RuNet: file hosting, photo hosting, image hosting, etc. But, judging by the polls of visitors to my forum and a lot of reviews on all kinds of resources on the network, I can conclude that there are more directions where you can develop regular image hosting or photohosting. But not enough statistics and statements. In this connection, I could not but pass by such a resource as Habrahabr, therefore I appeal to you. Dear, please, without any minuses (if you can), but simply from the bottom of your heart, write down who does not suit anyone in the popular modern photo hosting sites and image hosting.
For example, I propose to discuss: ipicture.ru, flabber.ru, picso.ru, smages.ru, avoreg.ru, ii4.ru, sharepix.ru, imageshost.ru, piccy.info - although of course, if you have your favorites or , on the contrary, in some service, something does not suit you, write. For all you are very grateful!
