I had observed a little weird experience with one of the forums where a spammer messaged me privately. And the room that was created shows me first as entered.

This is actually counter-intuitive. I had reported the same in that forum and the developers have confirmed that the forum engine (NodeBB) seems to be having this limitation.

I would like to bring the same for the kind attention of NodeBB team so that they can assess the feasibility of addressing the same.
