CyberGene That's a very interesting case scenario, name spoofing using confusable characters (similar looking characters but actually different). There's potential for anti-nickname spoofing extension/feature there.
CyberGene How long has that regexp functionality been broken for?
Not sure, but it has been patched now https://discuss.flarum.org/d/27852-flarum-v1-release-announcements/16
CyberGene BTW, is there an extension that would require a mod approval for nickname changes? Also, is there something like a mod/admin report that I will receive upon new user registration with details about username, nickname (in a fixed width font), avatar. Also, mod approval for avatar changes.
Not that I know of.
