Results of the game must be posted (as is specified by #1 rule above). The results will be a separate post from the host account...
Perhaps the devs could introduce a "reply to all commenters" function that a post creator could use to inform commenters on a post of a post modification/update. The "reply" comment would only be one entry on the original post, but all commenters on the post would be notified.
In this case, the separate post that you suggest could be a comment on the original post.
This is interesting as I am running a contest currently, and have been considering HOW to inform everybody involved of the results w/o a separate comment to each one.
Well I like the separate post idea if the script could auto-capture the names and provide them in list format on the 'reply post' itself. As it is a separate post, the host/admin of the game would get all the upvote-value of that post to keep for themselves, while increasing trust and transparency.
So I, for example, would upvote the original game post (per the rules) then would look for the 'reply post' to see if I won, how many others did, etc. And then upvote the 'reply post' as well as a tip for the game admin. A way of saying thanks. I don't think everyone would, but some will.
That makes sense
