If your objection is that "I don't want to engage with it" and "I don't find them useful", it seems obvious to me that the solution is to simply not click on the thread and move on, rather than to attempt to stifle everyone else from engaging with it.
I would assume there are counter measures and detection. I strongly remember people discussing up-voting rings/puppet groups that pushed stories on slashdot and reddit, and the counter measures used to prevent that.
I don't recall if dang has ever openly discussed such security measures, through I do recall him saying that people can loose access to flag/voting if they are misused.
