The question of who downvotes / upvotes seems to come up a fair bit in meta discussions. I recently noticed mention of a script that Anindo Ghosh wrote that identifies a list of users with a high downvote percentage and of course when you view a user's profile the same statistics are available as raw numbers:
My rating of 33% downvotes seemed about right taking into account all votes, but only if it included permanently deleted posts. Over a few days I took a careful note of what I'd downvoted and one morning found out of 12 downvotes the night before:
10 had been deleted for 'reasons of moderation' and accounts deleted (troll posts)
1 had been closed as not a real question but remained on site
1 remained open
On a second day I got similar results, while when you downvote answers that are later deleted you get back the
-1 rep but it doesn't change the voting statistics on your account. Not that I think it's any sort of problem that should be addressed I'm pointing out that using these statistics to judge user behaviour is largely useless.
Comments are welcome I'm just pointing out what I do personally (and presumably others) can skew results a lot on these overall numbers. Maybe I'm wrong but I think heavily downvoting trolls quickly reduces their chance to further spam the site because they'll get a ban on posting faster?
