I'm a high-rep user on Stack Overflow. I shouldn't care overmuch about downvotes directed my way. In general, I don't, except: I've asked only two questions; against hundreds of answers. A single user can downvote all my questions without triggering (as far as we know) the vote fraud algorithms. Questions are featured much more prominently than answers in a user's profile, amplifying the apparent effect of those downvotes.
I bring this up because I've noticed a pattern. Periodically, batches of my posts (including my questions, which are quite old at this point) will get downvoted at the same moment. This has happened maybe three or four times. I tend to vote-to-close about a dozen or so questions a day, and posters will sometimes make clear their displeasure at these closures. I suspect, but can't prove, that these users are going around voting down all those folks that voted to close their questions. If they limit themselves to one or two votes per closer, no algorithms (again, theoretically) will get triggered.
I feel a bit like a whiner bringing this up, but:
- I'm proud of my contributions to SO, and don't hesitate to point people to them, including from my resume. I don't want graffiti on my house, and I don't want garbage in my profile.
- I wonder what will happen when I have another question to ask - will the accumulated downvotes prevent me from asking?
I've written to the team before about this, and Jeff was kind enough to roll back a previous batch of downvotes on my questions. That's not a good way to deal with this, though. As it stands, I'm reluctant to vote to close bad questions.
I propose extending the vote fraud detection script to include this scenario. Roll back downvotes if the voter is voting down more than N posts by users who recently (successfully) voted to close one of their questions. Bonus points if the downvoted posts in question are quite old (and thus no longer visible).
Again, I can't say that this is a real problem, but I suspect it is.
EDIT: The question downvotes I received yesterday, and several others besides, appear to have been scrubbed from my questions.
