Click the "Hide from list" link on any curator's card. From then on, they won't show up when you submit. We'll ask you to confirm before hiding, since the change sticks until you undo it.
Why hide someone?
Could be anything: they're consistently a bad genre match, you didn't like a response they gave, they're not active anymore, or you're just trying to keep your submit list focused. Whatever the reason, hidden curators get filtered out of your submit flow so you don't have to keep skipping past them.
Unhiding
Head to your Account page and open the Hidden curators section. You'll see everyone you've hidden, with options to unhide individually or clear the whole list at once.
Hide vs. favorites
Hiding is the opposite of favoriting. Favoriting surfaces curators you want to see more of; hiding filters out ones you want to see less of. See the "How do I find curators I have favorited?" article for the flip side.
