No the talk to the moderator will not return. It turns into a circus.
Now onto some of the items:
Old forum allowed us to put a reason for deletion and it showed up in thread. That software was no longer supported. New software doesn’t have that option.
All sorts of things. Like the thread about users on the old forum started going more into attacking past users. So it got shut down. If a thread turned into a trainwreck with more deletions than posts left they can be closed. Trolling threads are closed or deleted.
It is impossible to send a message to every user for every deleted post. Example, a thread yesterday I deleted a posts that was nothing more than a “drudge report” type with links to about 30 articles with no discussion on any of them. When I hit delete, it deleted 48 posts with it.
It is actually getting harder and harder to find people to moderate the board. Last mod added was after several turned down the opportunity.
