I found this question shown on the "active" list, as in the following picture:

enter image description here

But I went though carefully on this page, none of the operations was done by "Community".

Is this a bug?

No, this is not a bug.

The Community user automatically bumps "old", unanswered questions to get them some attention.

This is confirmed by the "about me" section in the Community user's profile:

Hi, I'm not really a person.

I'm a background process that helps keep Stack Overflow clean!

I do things like

  • Randomly poke old unanswered questions every hour so they get some attention
  • Own community questions and answers so nobody gets unnecessary reputation from them
  • Own downvotes on spam/evil posts that get permanently deleted

Good idea. But I think change "randomly" poke old unanswered questions into "select" the old question that earned high upvote is better. –  Roy1 Jul 29 '11 at 6:55
    
@Roy: But that misses the point. We want to bump questions that don't have any answers so that we can get them answered. There's no reason to bump or poke questions that already have answers with lots of upvotes. –  Cody Gray Jul 29 '11 at 7:11
    
I mean "select" the old question that earned high upvote in unanswered questions, at least add more "random" weight to the more upvotes question. –  Roy1 Jul 29 '11 at 7:37
    
@Roy: The algorithm has been tweaked a bit recently. See this question: meta.stackexchange.com/questions/99672/… –  Cody Gray Jul 29 '11 at 7:45
