What happened after the form submission hit limit?

Dear Sir, what happened after my form reached the limit of 100 submissions ? how it show to my customer ? is the form still there and just cannot be submitted when click on "submit" ? or it totally disappear from my site ? 

Please note that warning email is sent when you reach submission limit and all your forms are disabled. Your users will not be able to submit form. When your form is accessed, it will shows  "Form over quota" message as displayed in the screenshot below:

Hope this helps.
