@Matma Rex and @AntiCompositeNumber, please see https://signatures.toolforge.org/check/it.wikipedia.org/Francesco%20Ippolito I don't know whether this is wrong or just appears wrong, but if feels like a bad idea even if it should be "legal".
Topic on Talk:New requirements for user signatures
Looks like the user was renamed, see . Everything redirects to the current username, but it boils down to the same old problem of renamed users not updating their signatures.
That seems like a local issue to me. This might be a renamed user and hence valid. It does appear wrong, though, and I would not personally encourage it.
Is there ever a use case for this? Maybe I have two accounts, and use the same sig template for both?
