Didn't know where else to ask about this so I picked FlyerTalk.
I logged into Marriott Bonvoy Insiders today as I wanted to post a trip report. I logged into my Marriott account and went to Insiders where I was presented with the below message. Couldn't even contact Customer Support as I got the same message. I selected Advanced from the first warning screen and got the URL not found message. Could it be that Marriott has said "Bon Voyage" to insiders??
