How hard would it be to look at it from the other side of "T0": what caused the community to want this ban? How did the number of reverts evolve over the years, compared with anonymous edits/total edits? Did the numbers/trends change when certain features (e.g. AbuseFilters) were introduced? I believe we also need to understand the internal landscape and dynamics leading to these radical decisions so informed decisions can be taken on what alternatives can be provided.
More details TBD
