@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.
I thought that everyone saw my IPv6 address in this page, which then does not doisplay the same thing for everyone. Anyway these entries are spurious, It reveals that there are effectively lot of logs being made for non-sense account creations by a bot, which then gets rapidly reverted. I suspect this occurs each time we connect on the site. But in fact I tried to disconnect and waited for some minutes before revisiting once, then wait for other minutes, and come back later to login: 3 actions are logged. Any visitor from any IP may have an IP account instantly created, and logged, even if that accoutn is not used at all for any write action, jsut simply visiting. This means that this site is easily attackable: you can have lot of logs filling your disks and the database, and the site won't resist at all. This may explain why the site is sometimes SOOO long to refresh itself and has many antique statuses that can take sometimes days to be reflected.
