When querying the /users/{ids}/reputation API route, the results don't include the +2 reputation changes from accepting answers.
None of the reputation results from my own reputation history have a vote_type
of "accepts" and a post_type
of "question", despite the fact that I've accepted 69 answers to my questions.
I've also looked for reputation changes of +2 and looked at the reputation histories of lower-reputation users to verify that these reputation changes are missing from the results.
