Last night when I was researching on an issue I can to a post which one of the answers had a Avatar Icon with text Moderator inside it. I cannot find that post today.
Considering that person reputation was lower than 50, I wonder if he could be a real moderator.
Do we have a guideline which explicitly ban this?(That is A none moderator uses the moderator icon?
I think no web site needs fake moderators.
The suggested(Duplicate) link says impersonation is OK. I disagree. A moderator should not be impersonated by anyone as people rely on them more than others..
