I have accounts on two kinds of sites:
ones I'm interested in (and with active participation)
ones that are heavily spammed (flagging is almost my only participation there)
But Blender.SE is in neither one of the above, so I don't have an account there.
Today SmokeDetector reported a vandalised post on Blender.SE, and I went to check it. What I saw was a +20 post, with no recent edit history. That confused me for quite a while before I noticed that the question ID was different. It then took me another while to realize that the "anonymous user duplicate redirect" mechanism was in effect, because I could see my red inbox and green rep change on the top bar. It was then clear that I was treated as "anonymous visitor".
Even if a logged-in user doesn't have an account on the particular site, can we please not treat them as "anonymous" for purposes of redirecting them away from dupes without an answer? Or at least those that have the association bonus?
