Created attachment 10852 [details] Screenshot See screenshot. He can evidently mark feedback as unhelpful repeatedly, despite it being the same piece.
Also mentioned in https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:Article_feedback&oldid=532148223#Bug:_Same_user_can_mark_feedback_helpful_or_unhelpful_multiple_times Example from dup bug 43208: http://en.wikipedia.org/wiki/Special:ArticleFeedbackv5/Mathematician/735459

What's actually happening from the screenshot is marking it unhelpful, changing your mind and UN-marking as unhelpful, repeat. That's a legitimate activity the first few times, though a little wasteful to log. The UI should clarify its behavior so some user doesn't repeatedly click thinking she is plus-3'ing or minus-4'ing some brilliant/awful feedback. For example, tooltip on the icon could show [Click to un-mark as unhelpful] or [Undo your marking as helpful], AFT could immediately give feedback showing the action, etc.
There's no reliable way to be certain that an anonymous user has up/down-voted already, so it could theoretically still occur with anon users, since we rely on cookies for this. This was a problem with the javascript however, which resulted in quite a decent amount of consecutive up/down-votes like this. This problem has already been solved for awhile now though.
