This is related to the comments on my previous post: Are dupes being redirected for non-logged in users?
Can we please put a linkback to the original question on all posts that were redirected (somewhat like we do with migrated questions) so that new users, who are not normally on this site, understand what happened.
Also, when the user is redirected, make it so the linked questions on the side (which are all duplicates) have the
noredirect set. As you can see here and if you click on the linked question when you are not logged in, it takes you back to the same place where you were -- aka a loop.
