I had a bounty on a question that a relatively new user posted an excellent answer for.
After awarding the bounty, I noticed that his rep went up by 200 instead of the bounty amount of 100.
After looking at his rep page, I saw this:
+130 35 secs ago 4 events What is the benefit of becoming a neutron star?
+100 35 secs ago assoc Association Bonus
Did I just accidentally force him to associate accounts somehow? Is this intended behavior?
