I don't think the paper has been accepted, because the conference itself has not made decisions on the papers. This article [1] says that the paper was submitted to "ACM Conference on Fairness, Accountability, and Transparency", which sends paper decisions (accept or reject) next week [2]. Of course, it might be accepted at that time, but that doesn't seem to be decided yet.
