I once tried to report an incident to a train line who had done "~a nice thing for a person~" and had photos about it on their social media. One photo was in their office and in front of a wall with a A4 page of usernames and logins for various systems on it.

I tried three different contacts I could find, only one came back to me and wanted to know what the systems did what the risk was etc. I pointed out I have no idea, and I'm absolutely not logging into mysterious systems to find out - pass it to your own IT so they can see what needs to be changed, rotated etc.

I did eventually get a message back from someone who thanked me for my diligence and said it was solved as they had now removed the photo... I really hope they had someone who understood look at it, but I decided not to engage further...
