Please read through these instructions before you click the link so you know what to do.
First, go to the following link HERE
Next under where it says "What do you need help with?" Choose "Getting into my account"
Next under where it says "Tell us more" choose "Get back suspended account"
Next click the red button that says "I still need help" this will open a form.
Fill out all of the relevant information and pinterest's suspension team will contact you. It may take 24 hours or more to hear back, once you hear from them youshould be able to get the account access back.
As I said though, I think pinterest is having an issue on their end as you are the second person I have helped in the last 2 hours who had the same issue.
If you need further help please let me know. Also if you have a moment please rate my service by clicking the stars at the top, 3 or more please to acknowledge you have received my answer/advice.
