A "Who posted" block?

[+Pavel Chernitsky 104]

Is there a block that shows a list of members who posted in a topic (obviously on the topic where the block is placed)? Or can one be made using the custom blocks?

Any help would be greatly appreciated.

I mean, it's more funny than anything else because there aren't that many results, but seriously, what the actual F...
