Well, that's the way things work here. That post wouldn't have been deleted in other forums, but usually too short posts that don't add anything meaningful are at risk of being reported and deleted.
In my case, I had some posts deleted after
someone considered one of my posts low value and went through my post history on a reporting spree.It has not happened again, I guess it is clear that I am a decent poster. Although I suppose I might get some post deleted in the future, as most people in the forum have.
I'm not sure the moderators have to interfere with the communication because of the length of the post, especially if they don't bother themselves to read all the rest of the conversation to see it was not just a casual comment.
