As part of a sockpuppet investigation, I need a list of all registered usernames on enwiki (excluding any that have been suppressed). This is essentially what T51132 is about. Would it be possible to get a one-off export in a file somewhere that's visible on spi-tools-host-1.spi-tools.eqiad1.wikimedia.cloud? For my immediate purposes, I only really need the names, so just one name per line in a text file would be ideal, but a SQL XML dump would probably be OK too.
I have a vague recollection that I've seen a username a long time ago which is similar to some of the usernames in a current SPI report. My plan is to use standard unix command-line tools to slice and dice the username list in various ways hoping to find it.
