Hard Bounce - Category 1 - Anti Spam

If there is a hard Bounce, category 1, Anti-Spam reason, Marketo sets the Email Suspended flag to true for 24 hours.  I understand that this email suspended flag=true never goes away unless you run a smart campaign to do so.

However, my question is this:  If a Category 1 hard bounce occurs multiple times on the same lead record, is there a limit to how many times this can occur before Marketo wil flag something else?  And if so, what else is flagged?  Is Marketing Suspended flagged at some point?

Thanks for any input out there...
