The whole 'scoring' system does seem woefully out-of-place on a support site; this really isn't the place for rating people poorly because they don't match up to one's own preconceived notions of 'perfection' or 'desirability'. The comments people leave are what's really meaningful, anyway.
I've always thought the rating system should be removed for the reasons you've stated. Seems almost arbitrary on a support site to score cocks when it's more supportive to leave comments. In the end, numerical ratings mean nothing to me but I always leave a 10. When I post a comment, I want the poster to know why I took the time to admire them. And THAT'S why the galleries exist, IMO. If you don't like the pics, shut the fuck up and go elsewhere.
If someone wants to rate a photo poorly, I at least expect them to be man (or woman) enough to state their reasoning for doing so. Generally, these non-posting n00bs with no galleries of their own (and they
always fit this profile) simply retreat back under the stone they just came out from, though.
Had the poster in question accidentally posted a 1 not knowing how the rating system works that would be one issue (it's happened before) but a 3? Someone who pulls that shit usually has insecurity issues. Same thing if they leave nasty comments in the gallery or troll around the board giving out unasked for derogatory opnions. They're only happy while trying to make others miserable.
