Every ad except this one was suddenly downvoted, taking many ads out of rotation. Does this constitute vote fraud?
Edit - As suggested, I've downvoted the offending ad to even things out, since this is apparently acceptable behavior / the recommended course of action. Case closed, I guess.
Edit 2 - I've taken everyone's advice to heart and downvoted everything but projects I'm interested in. I welcome everyone else to do the same. If just a few more people do it, we'll have only a Vim ad. Maybe in 2h we can just skip the voting and run a Vim ad and nothing else, it will be much simpler.
Also feel free to jump into the feeding frenzy and downvote this question into oblivion. Help me improve my Meta Golf score.
