I'm pretty sure this might be a problem confined to v/TIL because I posted to that sub after if was anonymized by the mod and shortly after my post was made there, Puttitout reversed that anonymization. So that part went well and my anon post at the time remained anon.
During the time the sub went anon a few posters also mentioned the v/TIL sub was "locked" so I made a comment in a thread here to see if it was true:
You can see here: https://voat.co/user/Cuckbot/comments that comment clearly being shown in comment history. If you see this post later here's an archive of my comment history in case it's buried: https://archive.is/mglRr
I also recently made comments in a few other Anon subs and they don't show up which is why I think this just might be a hiccup with that sub. I don't really know if this could lead to a bigger issue with real anon subs or not so I'm just letting you admins know.
PS: clicking the Anon ID in v/TIL does not lead to my profile.
