User shouldn't be able to vote his own post and response. Additionally, user shouldn't be able to report his post/response/comment.
The controls should be hidden if a thread/response or comment is user's own.
1) Login to edx app.
2) Create a new post/response/comment in discussions.
3) Try to vote/report post/response/comment and view.
Both and aren't priority fixes and I would suggest removing (this story) from the active sprint. cc'ed
