Today morning when I logged in to Ask Ubuntu, all of a sudden my reputation points changed from ~7000 to ~7300 but there are no traces. How is this possible?
How can I trace these reputation changes? Also I was getting reputation +5 for a Question up voted to me. But I am getting +10 roughly after reaching 7000 reputation.
Global Rep Adjustment.
Read "We're rewarding the question askers" on the StackOverflow blog for details. They started implementation yesterday. (Upvotes on questions that were +5 are now +10 so you gain rep from this recalc)
Mods have more details on this than end users do, though, so I'll include this tidbit specific for your reputation for this inquiry only:
Global Recalc: question upvote value change old rep = 7024, new rep = 7364 by Community
(this is moderator-visible only in the tools, which is where I got this from. Everyone has a similar entry if they've posted any question that's gotten upvotes on the site.)
This is because network wide reputation recalculation occurred last night. Earlier an upvote on question used to award +5 reputation points but since yesterday it would award +10 (equal to an upvote on answer). The change was made retroactively, i.e., the reputation was awarded as if it was always +10. You can have a look on reputation page.
You must have a total 60 upvotes on questions, thus adding extra 300 (5*60) points. For more info, read the blog post by Sara Chipps.
