Will going over the submission storage limit cause my forms to be disabled?

Hi, I ran out of storage space because I have >500 submissions.  If I choose not to upgrade, will the system simply start deleting my form responses from oldest to newest?  Or, will people be blocked from submitting forms?  Thanks,

Submission storage will not cause your forms to be disabled.  Older submissions will simply be hidden and eventually deleted.  All other limits will cause forms to be disabled, submission storage will not.
