Mechanical Turk Account Suspended: No reason given

I attempted to log into my mechanical turk account today and I was notified by the page that loaded in my browser, "There is a problem with your Amazon Mechanical Turk account This account has been suspended by the Amazon Mechanical Turk team." No explanation as to why; no link or information given to contact anyone regarding the matter...

I checked my email searching for any thing (queried: "Mechanical Turk"). The last thing I have is a"Annual Privacy Notice and Account Updates", dated 05/03/19. Prior to that the last thing I have is a "Weekly Worker Activity Report" dated 09/21/15. Yes, it's been about five years since I've used the account. What happened, when, and why I'd like to know, and please be reinstated.

Thank you
