Hi Trello support team,
Our organization don't use Trello product, but we got many email with subject "(My name) From (My Company name) invited you to a Trello board 3 days ago". When clicking on the link in the email (trello.com/....), it prompts to join the board. That board was not created by any of us. In the board, there is card with a document inside but not relevant to us.
We guess this is a bug on Trello that allow someone (not from our company) to invite us to their malicious card/document hosted on Trello.
We couldn't raise the private support ticket because we don't use Trello at all. Please contact me for more details. This issue is annoying our organization with daily Trello invitation emails.
Thanks
