User blog comment:GuacamoleCCXR/... and this is why reading the rules as a Mod might be helpful./@comment-4845243-20130426154752/@comment-4845243-20130426170709

The rule only talks about giving your own first name, as I already said. So it is silent on giving out other people's first names; thus it was not a violation of the rules to ban, despite being unnecessary in that particular situation.
