Ratings Abuse Rearing Ugly Head at BT?

I just had the lovely experience of discovering that someone gave one of my posts a “1” rating.  A post which, as any reasonable person can see, doesn’t even come close to deserving that, or a “2” for that matter.

And this poster appears to have only a short history here, and may have previously posted at other blogs where ratings abuse is rampant.  It had never previously happened to me here, though, something I really valued about this place.  I know that for obvious reasons BooMan wants to be welcoming to these new posters, but I would really love to see him come out strong on this ratings abuse issue and nip it in the bud.  Otherwise he might find he loses a bunch of his stalwarts in exchange for the “new kids” and their hair-trigger culture.

Has anyone else seen signs of this kind of abuse, or is this an isolated case?
