Does Socratic have a "report answer" system?
Technically, not yet.
Back in the day, Socratic used to have a more extensive flagging system that included flags for abuse and spam. In this regard, members of the community could mark unwanted content by flagging answers.
About 18 months ago (give or take a couple of months), the flagging system underwent some major changes. The team moved away from the original flagging design, which pretty much meant that users could only report answers by talking to a moderator.
So technically, we don't have a report system at the moment. The good news is that a new system is currently being designed, so look for an update on this soon.
Until then, you can report answers, questions, or users by sending me a note. I'll swing by as soon as I can and investigate! :D
