What can cause my question to be "bumped" to the first page in the Active tab of a Stack Exchange site?

Given that this related question was closed as a duplicate of this FAQ entry, could someone please adress the aspects of that question not already in the answers here (be it only by comments if it's just always "if not already mentioned then no")? I.e. Is there anything that can prevent the hourly Community bump to happen and is the choice of the respective question really random, without any bias (like e.g. votes or views)? –  Christian Rau Aug 13 '14 at 15:53

The following will cause a question to be bumped:

  • Addition of an answer
  • Edit or retag of the question, or edit of an answer* **
  • Addition of a bounty (by anyone)
  • Successful reopening (if the question was closed)
  • The Community user will bump non-negatively scored questions that have at least one answer scoring 0 and none scoring more than that. The number of unanswered questions bumped per hour depends on the site: 4 per hour on Stack Overflow, 1 per hour on Meta, and 2 per hour on Super User and Server Fault. The default for a new site is 1 per hour.

The following will not cause a question to be bumped:

  • Deletion or undeletion of the question or an answer
  • Upvotes/downvotes on the question, answers, or comments
  • Close/reopen votes on the question
  • Flags (offensive/spam/moderator)
  • Creation or removal of comments
  • Pending edits
  • Accepting an answer
  • Protecting or unprotecting the question

* This holds true for edits that generate a revision in the post history. Edits on a post within 5 minutes of its creation or another revision-generating edit fold the changes back into the previous revision, and do not cause the post to be bumped

**Questions with sufficiently low score will not be bumped when either they or their answers are edited. The "sufficiently low" threshold is -4 on SO and new SE sites, and -8 on MetaSO (as of Aug 25, '10 -- see Grace Note's comment).

•The Community user will bump unanswered questions every hour. - that's questions with 0 answers, or questions with unaccepted answers? –  Mike Sep 21 '12 at 19:25
@Mike: 0 upvoted answers. –  Second Rikudo Mar 23 '13 at 8:52
I don't think that a rollback edit causes a question to be bumped. –  Andrew Mao Mar 26 '13 at 16:02
@AndrewMao so you're wrong. Rollback is considered a full revision thus changing the question "last activity" timestamp. –  Shadow Wizard Apr 3 '14 at 12:37
Close/reopen votes won't bump; a successful reopen will. How about a successful close? I have no preference, but I'd like to know. –  Ziv Sep 1 '14 at 9:31
