I have the exact same problem! I use Multisite (Sub-directory configuration).
I have set the same Disqus “Forum Shortname” for each of my sites, but sadly, after syncing the same new comment is duplicated to every site. Comments are not glued to the particular WordPress site, so fix is really needed…
Currently there is no ability to have ONE Disqus forum operating all WordPress Multisite sites.

I’ve used the same shortname across multiple websites. When a comment is posted it gets synced to post it was made on and any other post on the other websites with the same ID.
Is there a filter I can add to make sure that comments only sync to the website they were posted on, or do I have to go with a different shortname for every website?
