Forum: Go to original post -> Click More -> History -> You see something like "User1 removed User2's reply #23" -> Go back to original thread -> In the URL you see Thread:717789, add the number to it, ie Thread:717789#23 -> Enter and you can see the post without restoring it. (I'm pretty sure there is a script to make this easier.)
I thought I remembered seeing something about this, but I don't think it's possible (I could be wrong). The best I can say is patrol the threads and issue a block if the deleting gets out of hand. In the meanwhile I found the script to see what forum thread posts have been deleted faster when you see them: Thread Inspection. There has been indication by Staff that more control over the removal of posts is likely to appear in the future.
Now, you go onto their wall, click the timestamp of the removed comment, say 13:50, August 6, 2017, and it'll show, whether it was removed or not! For anyone googling how to view and they cant find out how. Like me..
