I can't remove someone's comment from my screenshot because they have blocked me

[gold diggers and black ni]

A scammer commented on one of my screenshots (the only one I have, TF2). I knew it was a scammer so I wasted his time but then he blocked me and now I can't remove that comment.

The "delete" button does nothing.

You might take down the screenshot and re-post it. This way the comment will disappear.

Blocking you doesn't prevent you from deleting their comment. The account is community banned.

Just ask support to delete it.

Found a solution: enter big picture mode and delete the comment!
