I have not read this entire thread so sorry if this has already been brought up, but...
Is the only way to report a person in detail (with a short explanation of why you are reporting them) to contact a mod directly? I have just recently discovered that flagging a post offers no options for explaining why one flags the post, and there is no button that I can see to report a user for anything, only a users posts. There may be cases, however, where all of a person's posts looked at individually are perfectly fine but looked at as a whole indicate a pattern of harassment or stalking. The proper way to report this is unclear with the current format.
