Fair enough, and exactly responsive to my query. A bit of common sense would seem nominal to extricate anyone with good faith from the problem. However, I personally have observed users being perennially DV'd on content that doesn't run afoul of that standard, and while I cannot state HW alone is responsible, the relationships between spaminator, Marky, and a variety of others I note practice that behaviour are opaque and cannot be confidently ascribed to any particular source, nor exclude any. As I am addressing you, I can only address things I have observed you to do.
Do you DV creators and accounts on content that does not feature such lapses in attribution just because they once did fail to do so? Do you limit application of DV's to content that is failing to properly attribute non-original work and personally editorializing or otherwise contributing original work, as you outlined above?
