How long do you keep bounced leads?

[Kelly_Harman1]

We are trying to decide the right amount of time to keep hard bounced leads. We want them long enough to do analysis and make sure the reporting does change but we also don't want to have to store them for a long time if they are not use-able. Has anyone found a sweet spot for this?
