Currently appr will create a new comment for every build in an open PR - most commonly this means for every push, which can get a bit spammy.

Consider making the user experience better by amending existing comments, or if we still want to post a new comment every time, at least collapsing the content of older comments.

Danger does this quite well. We could see if we can use Danger internally, or more likely, just get inspiration of how it works since we may not want the full danger comment format.
