@iliazeus @drq i suggested idea here: secondary answer not shows as regular post with thread, but mark "also answered in" with link to post under first reply source.
Also, optionally we may draw this post's contens (but not other replies). Clicking to the post will jump to thread point, where first "reply to" was and loads thread if it's another thread.
But this allow user to create many such replies, flooding notifications, many separate posts. Very useful for spamming/flooding.
And we may draw all "Reply to" posts with contents except first as same links in replying post to allow see, what post referenced before opening link (maybe hidden by default to not flood the screen)
@mittorn That's where you file a report, and we get rid of the bastard.
