Years ago I had the idea that advanced civilizations can radiate waste heat into black holes instead of interstellar space, which would efficiently achieve much lower temperatures and also avoid creating detectable radiation signatures. See http://www.weidai.com/black-holes.txt and my related LW post.
The recent news about KIC 8462852 immediately reminded me of your old txt file article. I’m really curious what you think about the recent information given how much you seem to have thought about advanced civs.

It’s an interesting idea.
Stable black holes seem difficult to create though—requires alot of mass. Could there be a shortcut?
