Everyone sees their own ip. The users in those log entries no longer exist and those log entries should not be there.
What do you mean ? We don't see the same things in logs ? How can you be certain we have the right to see "deleted" log entries? Just because at one time we are using the same IP ? Anyway I do see all these log entries (about 4-5 listed each day since August 15, not any one before, but I see them in the log just since a few day; I many have not noticed that before). So you say that these log entries "no longer exist", but then why do I see them ? Was there a bug that caused IP accounts being created for logged in users, then immediately deleted after logon, but recreated later and repeatedly ? This is clearly a bug: there should not be any account creation before we submit an actual edit (just reading the wiki or logging in should log nothing, or you have a serious privacy issue for RGPD).
@Verdy p: The IP address I see is the one I'm using. It's not an IPv6 address. I agree it's a bug, and should be fixed, but there is no privacy breach when everyone sees their own IP address.
