Imgur runs it's own servers. They don't have to run a separate host like sli.mg has to.  Imgur works fine if you don't publish your images to the site's social network. Is there any reason not to use it?  They CLAIM that. Yet they have removed tons of images from people (including fph mods) who had their images not published. They are full of shit. Plus they are fat fucks and are in reddit's pocket.
