Description

Interesting output at https://meta.wikimedia.org/wiki/Special:GlobalUsers/a doing unrelated things.

Those usernames with @ or starting in lowercase should probably be batch renamed to Invalid username~xyz as done with previous cases.

Well, it goes far beyond what I thought. If we search for "a" then the list is bigger. I'll update the paste.

On this page there are two which link to [[Special:CentralAuth/]]: https://meta.wikimedia.org/w/index.php?title=Special:GlobalUsers/%E1%B8%81&offset=%E1%BD%99%CF%80%CE%B5%CF%81%CE%AE%CF%86%CE%B1%CE%BD%CE%BF%CF%82+%E1%BF%AC%CF%89%CE%BC%CE%B1%E1%BF%96%CE%BF%CF%82 and one which does not link anywhere

<globaluser id="32311475" name="                " />
<globaluser id="32311476" name=" " />
<globaluser id="27367943" name="‍" />

as the link will outdate probably.

<globaluser id="32311477" name="‪‪" />
<globaluser id="32311478" name="‪‪‪" />

Then of

<globaluser id="38039199" name="‮" />
<globaluser id="27368904" name="‮Romeo" />
<globaluser id="27368905" name="‮Tiewtew‭" />
<globaluser id="16873304" name="‮iv‭" />
<globaluser id="38039200" name="‮iv‮" />
<globaluser id="32311479" name="‮‮‮‮‮‮‮‮" />

some give link, some not, but both in API and in normal interface they mess up with direction badly

(I have to check what was initially written here)

We have a lot of bugged accounts like that. Some with special symbols may not be able to log in at all. Personally I would remove them since they can not be used at all due to system limitations.

I noticed on eswiki a couple of usernames that contained an @ on their usernames, so I decided to dig a bit: https://quarry.wmflabs.org/query/32380

MarcoAurelio renamed this task from More invalid usernames to Rename global users with invalid characters on their usernames.Dec 30 2018, 10:07 PM

MarcoAurelio added a project: WMF-General-or-Unknown.

Also (and displays as broken as below on Special:GlobalUsers):

[[Special:CentralAuth/~~~|~~~]] (unattached or doesn't exist locally)
[[Special:CentralAuth/~~~Flo~~~|~~~Flo~~~]] (unattached or doesn't exist locally)
[[Special:CentralAuth/~~~~|~~~~]] (unattached or doesn't exist locally)
[[Special:CentralAuth/~~~~~|~~~~~]] (unattached or doesn't exist locally)
[[Special:CentralAuth/~~~~~~|~~~~~~]] (unattached or doesn't exist locally)
[[Special:CentralAuth/~~~~~~~~~~|~~~~~~~~~~]] (unattached or doesn't exist locally)

https://meta.wikimedia.org/wiki/Special:CentralAuth/_59.86.41.24 is also listed in GlobalUsers but its broken.

Similarly an account whitespace (_) exists but leads to https://meta.wikimedia.org/wiki/Special:CentralAuth/ which is also broken.

Someone has to actually run rename queries, I am not sure if Operations is the right choice but hopefully some hints are made.

I think that is done by DBAs and not Operations (someone correct me if I'm wrong)

No, that's not run by us, DBAs.
Maybe @Legoktm can help up?

MarcoAurelio mentioned this in T246815: "Ghost" accounts in Special:GlobalUsers.Mar 3 2020, 7:05 PM

There are 40941 global users with an @ in their username.

MariaDB [centralauth_p]> select count(*) from globaluser where gu_name like "%@%";

I think the number of users with invalid usernames is quite big.

Adding @sguebo_WMF.

Per T308159 and regarding accounts with potential PII on it (e.g. accounts with an that are email addresses) renaming them is probably not a good option, as it'll leave traces on the page move logs, the global rename log and the local user rename logs of every wiki the account is registered, unless you can create a method to do so silently. If they've not editted anywhere (no local/global edits) another option would be to globally suppress these via the CentralAuth lock+suppress option. If the number of accounts to be suppressed is too big, maybe this shouldn't be done via the web interface but using a maintenance script.

Accounts with edits or log actions should perhaps be renamed silently (no public traces) if that's possible, to avoid breaking authorships or leaving the DB in an inconsistent status.

For accounts with invalid usernames without possible PII, a server-side maintenance script can be run and globally rename these as it happened e.g. on T5507 or T219279.

Note such usernames will break BotPassword, see https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/e78541e80ff2b906bfa6a500f78f40e6054f40b7/includes/user/BotPassword.php#444
