If you go to Superuser and scroll down a little, there are many entries with Splattne's name against them. I have gone in and can't see any sort of change, retag, answer or deleting.
Is this something the system does at random? However, why is it with a mods name instead of community or similar?
I looked in the tools as well, but I saw nothing under closed or deleted and as I haven't see this before, I couldn't help but wonder!
