A stranger just added me to a Trello board, and the options for leaving the board/organization and commenting are turned off. I am worried now about the privacy of other boards tied to this account. Any way to get off this board and also prevent this from happening?
Contact FogCreek directly and ask (they are awesome). Since this is a security concern, they'll help you promptly ...
The same thing happened to me by viewing the board at websitesfortrello.com I can't get off the board. When I chatted with the guy at the websites site, he actually told me i had somehow given him the power to change and even delete my other boards. I have contacted Trello and am awaiting a response.
Very concerning, even if the guy was just messing with me, I ought to be able to remove his board from my Trello Account
