On mobile, Imgur has the most distracting, obstructive, and bewildering modal window I've seen. I'm not being hyperbolic; it's worse than the dark patterns on Forbes.com. It's in the form of a cat's claw, animated – sliding and extending from the top of your screen almost to the bottom – and slow, making users either click it accidentally or wait in frustration until it can be closed. Despite having seen it countless times, I still don't even know what it's designed to do or what action it's prompting me to take (e.g. login, capture my email address, etc.).
