Can I report an Avatar?

One Avatar I see around is scary and makes me forget what I wanted to say. So I just want to make it go away.

You can go to a user’s profile and click “report this user”.
 
However, unless the avatar violates our rules, it will not be removed simply because you find it frightening.

Still no harm in trying I suppose.

Use personal browser addons that let you block specific images, such as ublock origin.
