This question already has an answer here:
I discovered last week that an elected moderator can modify a user's name.
The user had a username that was clearly meant to insult one particular elected moderator. This was discussed in chat, and the moderator decided to make a minimal change to the user's username.
While it was funny to see this happen to an obvious troll, it did make me wonder. I'd have expected that only Stack Exchange personnel would have this kind of power.
So the question is - what else can a moderator do to my profile?
For example, can a moderator also completely rewrite the "About me" section? I can understand that under rare circumstances, material must be removed from these sections. But I would have expected that elected mods would only be able to make these things go black. Could they also completely rewrite it if they wanted to?
