Lewis, you're a HELPER not a MODERATOR, as such it's not for you to change ratings unless requested to do by the OP, MrPoopyPants did this previously and argued about the logic behind it, he had his helper privileges withdrawn, and got all butt hurt and ended up being banned.
It's not about debating what the rating was / should have been (I agree it's an obvious negative) but it's taking a helper issue and acting like a moderator.
I wasn't aware of any of this. No one has ever told me I had "helper" rights. I've just been through my PM's in case I had been notified, but have found nothing from Admin about it.
I'm not getting out my pram about it. Sorry if anyone thinks otherwise.
I'm certainly not arguing the logic behind it. I just saw that the option to change the rating was there. I hadn't seen it before.
I took it from granted everyone else had the same option. I wasn't aware that it would make an instant change.
I thought it would ping a message to admin (in the same way reporting a post does) requesting if it could be changed.
I was only trying to be helpful. Not my fault that I'm not clairvoyant

Now that I know about it, the mechanical workings of it, etc. I certainly won't be abusing it.
All I'm saying is that it would have been nice to have had a heads up about it, and the do's and don'ts.
I'm sorry if I've caused any problems. That was never the intention.
