What was funny is if their service is working good - i.e. someone linked an image from their site and it displays for the user - you don't even notice the work the host is doing.
But when they pulled an image and you're just shown a placeholder "PhotoBucket - image not available", you actually see their name and logo and have repeated negative associations with them. I know when I hear any of those names I just get pissed thinking about all the old forum posts and rotting internet pages I've stumbled across with the images missing.
