Admittedly a very minor bug, perhaps even a one-time thing.
This suggested edit on Science Fiction and Fantasy states that user Stormblessed created the stormlight-archive tag's wiki on Feb 17th, 2016. Except their account didn't even exist until 5 months ago (we SFF folks are open-minded about time travel, but still).
The attempt at repro
I'm posting that here instead of SFF Meta, as I think it could happen elsewhere on the network, but it's not something I can easily check (as SFF is the only site where I'm >10k and can access review history).
So what gives? Is it a one-time thing not to be bothered, with or is there a repro somewhere else?
The search for a possible dupe
[bug] [tag-wiki] [suggested-edits]doesn't seem to yield anything (unless I missed one). Admittedly some questions might not be correctly tagged;
"Similar Questions" algorithm suggests The user who first proposed a tag wiki is treated as owner for suggested edits - but in this case, editor was not the tag's creator, nor were they the one to write the wiki's previous version.
