I had a problem with this a little over a year ago, and had the same opinion regarding moderator actions. Apparently the warnings get tacked onto whoever made the post that was reported. Context is rarely checked, and so other potential offenders are missed. My advice is to report & leave the thread instead of stirring the pot. Stupidity abounds, but you don't have to stick around to see it.
Which isn't to say I always follow my own advice.
