How to bulk delete Cards in trello

[Keith Kander]

My Trello adds a significant number of Cards when I log in. I am up to 11000! How do I disable this and delete the cards that have been created/

Hi Keith,

Trello certainly shouldn't be adding that many cards when you log in, so it sounds like there might be something else going on. The only bulk delete feature Trello has is manually, via the API: https://developers.trello.com/

If you can write in to us via https://trello.com/contact, we'd be happy to take a closer look at what you're describing and see what's happening!
