What does parameter $3 indicate in these messages? Is this a username?
The documentation for both messages say that $3 is "the affected page":
@MarcoAurelio: Since you're a steward, do you have a way to try touching both logs (or, have you did some actions in the past that touch both?), so that we could know which "page" the $3 points?
I think $3 means the IP or CIDR being locally whitelisted or de-whitelisted.
I did some testing at <https://es.wikibooks.org/wiki/Especial:Registro/gblblock>. Indeed $3 seems to be User:<blockedIP/blockedrange> being whitelisted. I'll update the docs.
The problem comes from Template:Logentry which has hardcoded settings. It's not something we can change from gerrit unless we rewrite the entire message. Maybe we can amend the template so it is more customizable. Ping @Nemo bis and Nikerabbit:.
