Some strange anomalies are reported on Japanese Wikipedia.
I am not sure if this is a bug in software or something else,
so I am reporting it here first.
#1 Three users indicated that their edit records include
edits they had never made - wrong attribution.
#2 One of those users reported that while he was editing,
he "became" another user - he was logged on as another user.
He could see email address, watchlist, etc. associated with
that account. The account he was switched to was also among
one of the three users mentioned in #1.
To be more specific, the following three users reported
wrong attribution.
http://ja.wikipedia.org/wiki/%E5%88%A9%E7%94%A8%E8%80%85:Avanzare
reported his edit record include edit(s) he never made.
http://ja.wikipedia.org/wiki/%E5%88%A9%E7%94%A8%E8%80%85:Trashwriter
said that he had never made this edit:
http://ja.wikipedia.org/w/index.php?title=%E4%B8%AD%E4%BA%AC%E9%AB%98%E7%AD…
http://ja.wikipedia.org/wiki/%E5%88%A9%E7%94%A8%E8%80%85:Kunipoo
said that he had never made this edit:
http://ja.wikipedia.org/w/index.php?title=%E3%83%98%E3%82%A2%E3%83%8C%E3%83…
Also,
User:Trashwriter reported he once became User:Avanzare.
User:Kunipoo reported he once saw the user name displayed at
the upper right corner became NNNN or NNNNN. He experienced
other error messages and slow responce when this happened.
(User:NNNN and User:NNNNN do exist in Japanese Wikipedia,
although the former has only one edit and the latter none.)
Is this something that might occur in relation to server
overload?
Best,
Tomos
