Patreon is up there.

Most of the page is just wasted white space, the menu collapses randomly to little icons (guess so we can have more whitespace), the video feed is a small strip between the white space with only one video per column, ensuring you can never fit more than 3 on the page. The player somehow stretches across the fill page width, replacing some of the wasted white space with wasted black space. And that's just the interface.

You also have to unsubscribe from like 7 mailing lists per creator, individually, no option to disable entire lists (or they don't work). They also randomly add new lists which are by default enabled so you have to go through all your creators again. Oh, and if you click too fast when disabling their settings, sometimes it won't save ... at some point I just made an outlook rule auto-flagging all their mails as spam, because fuck that.
