We've spoken recently about the great recalc where anomalous voting patterns were wiped clean...and some people have asked about "stalking"...where you follow a user around because you appreciate some of their answers, and want to check out (and possibly vote up) other answers they may have.
I recently did some anti-stalking...where I found I recognized a user (whom I've seen give horrible answers before) give a new horrible (and offensive) answer. This was bad enough that I wondered, 'gosh, what else has this person done?', and I looked at their other answers, and ended up marking another couple down.
(lest the curious wonder...this is a user with fairly low rep, and who is not overly active...)
Now, I'm not terribly worried about a recalc...if the algorithm decides that these few markdowns are inappropriate "revenge" and wipes them out, it won't matter to me overly. But does this seem like reasonable behavior? I've followed a few people around and voted them up a few times, but specifically following someone to look for other items, expecting to find some more bad ones...well, it gives me pause.
I do feel that I only marked down items that deserved it (and one item they've posted got marked up), so in that sense I'm pleased with it...but does seeking out a person's answers expecting them to be poor/offensive strike people as morally suspect?
I think I've decided how I feel about it, but I would be interested to hear what other people think.
