You forgot to mention coin, who was unbanned a while back with no such announcement. Also, why is is that these particular folks were unbanned and the others were not? Was it the number of posts made after requests for silence? Was it the degree of vitriol or trolling in their comments? Was it that they apologized for their actions via some channel to the mods? Did someone still in the community advocate on their behalf? If the other bans are justified, what error in judgement led to the bans here that are being revoked?
Honestly I doubt that it will be shared - I get the impression that the mod team doesn't care for their decisions being questioned. But it'd be nice to see a gesture towards admitting error and all. Not nice enough to make most people want to come back, but you know. A basic level of decency and accountability.
