This means that the Footsite you’re running on has temporarily blocked your card because it has been been used too many times within "a launch".
A very common way to get this error is if you're using a test or fake credit card on your tasks.
Please Note: A launch isn't one release or one day. They usually reset limits every few weeks, not every day. We advise using a different card as you'll continue to get this issue if you simply restart the tasks that have gotten it.
