When confronted with horrifically Kafkaesque opacity, one can only retaliate with sunlight.
This is an accidental find:
What’s happening to one of my answers on Quora? Are there upvote bots?
From the details:
UPDATE: After an investigation, it seems my answer was targeted by spam bots or spam profiles (unknown reasons). Attached is the message from a Quora Moderator. It pays to colour within the lines and to report suspicious activity!
So, whatever else it may mean, “suspicious activity” is a new word for Spamming.
EDIT: Maybe. Though this putative moderator was themselves banned, and the ban wording was “The content was deleted because it is in violation of our spam policy”: The Mystery Moderator. So my conclusion was premature.
P.S. I’m fascinated at my spontaneous themselves just then. It has a specific referent alright, but one whose true identity (and thus true gender) is under dispute; so I used the gender-neutral alternative after all…
