@amimuson said in his answer:
"High reputation" is a generic way to explain what happens that isn't super confusing. A help center article isn't meant to go into all the explicit details, but rather just highlight the generic functionalities. Users get held up based on their number of votes and/or the number of people they've voted for. Reputation is not actually considered at all in the check. (Emphasis Added.)
This does not make sense. Obviously, the Learn More explanation following User Was Removed has created a lot of confusion among many users, most of whom are experienced users on at least one site, and not easily confused. Moreover the Learn More explanation is obviously incorrect, not merely simplified for the easily confused. As its last paragraph states:
This removal occurs whenever a user is deleted, unless that user had a very high reputation score. Because high-reputation users have usually cast a great many votes, removing all of them could be that much more disruptive to other users. In such cases, the staff use a special deletion that preserves the votes, resulting in no reputation change for those who had been voted on by that user. (Emphasis Added.)
I suggest the following edit:
This removal occurs whenever a user is deleted, unless that user had been very active. In such cases, the staff use a special deletion that preserves the votes, resulting in no reputation change for those who had been voted on by that user. There are circumstances, however, when the removal may occur even for deletions of very active users or for serious infractions of SE policy whatever the activity level of the deleted user. Go Go to [link] for a more complete explanation. (Proposed edit emphasized.)
The proposed edit is now a second draft, and could undoubtedly be improved. So, improve it. Or throw it out and rewrite it. Don't leave misleading info in a prominent place. If there is an explanation which is correct, give the link to it. Please!
Second Suggestion
The Powers that Be on SE must have known that the recent action resulting in massive removal of rep points across the universe of SE would create a major kerfuffle. Why not post a short, simple notice on all the Metas of the sites affected saying, in essence:
We have taken an action that has resulted in the removal of many reputation points for many users on many sites. Rest assured that we were obliged to take this action, and that it was thoroughly discussed and reviewed. We are sorry, but it is impossible to reverse any of the reputation losses.
Again, this is a first draft which can, and probably should, be edited.
Bottom line: Don't treat us like mushrooms!
