Removing question mark from system moderation

[Andrew H]

It appears that on forums running xenforo, some of them have a question mark for posts that are moderated, is there any way to change this to some type of “administrator” avatar or use the avatar of the moderated that modified the post.
@Akimbo are you aware of how to change this?
Below is an example of the question mark avatar
