It is only curiosity. I know, moderators aren't suspended; first they are de-modded. After de-modding, they can probably be suspended, but I've never heard of it happening.
Maybe it is possible if the moderators are fighting, but I think it would cause a CM intervention with at least one de-modding.
Thus, this question is a purely theoretical question. So:
- Can moderators suspend another moderator?
- If a moderator is suspended, (but not de-modded), can they use their moderator powers?
- If a moderator is suspended, can they use the normal, reputation-bound privileges of the ordinary users?
