How can unclaimed nodes be in swaps?

I will investigate. Thanks for highlighting this!

This was actually my friend. I spent about 10 hours helping him setup this node, and he made a mistake and closed all this channels, I'm not so happy about the time investment.
I can't say for sure, but i suspect he deleted his account to avoid the shame.
We all make mistakes, but as lightning grows there will be more and more newcomers arriving who will make mistakes - we just have to be understanding a little as people learn.

ouch... yea, mistakes happen, and it didn't cost much more than a few dollars.... he should not worry!
