What reasons would you expect to be in there and what purpose would it serve? Mainly to tell the moderators who would review it why it should be deleted, or for something else?
We haven't added this so far because there has really only been one reason why comments should be flagged and deleted, and that's if they violate our terms of service. With user-created streams there is now a potential second reason I suppose, which is "violates stream rules" since stream rules can be more curated and specific than the sitewide rules.
