The reason the subject came up at all is because this instance was particularly blatant. Otherwise, we don't generally have enough information to evaluate other scenarios reliably--this is why Eliezer wants a way to monitor voting abuse.

Even so I'm willing to grant that it could be something innocuous (and will apologize if that is the case), but the evidence so far leans toward abuse.

If you want to promote discussion about the issue, a top-level post is probably in order, as you yourself previously noted; feel free to make one.
