Thank you, it is reassuring to hear that it is in fact possible, and not just my imagination.
However the lack of restriction on suggested messages seems like at best a breach of user trust and at worst a vulnerability. Even as admin, I shouldn’t be getting suggested private messages that aren’t for me and don’t @mention me. What is the reasoning behind allowing this? Does it only apply to staff accounts, or can all our users have other people’s private messages suggested to them?
