Well, I dislike two things about the "health meter", but it's not what you'd expect.
1. I can see other people's health meters by going onto their profiles. Thus I must assume that they can also see mine. Personally, I think my moderation history, even if it is just a graph that shows how many times I've been moderated, is none of any other regular member's business. That should stay between the member in question and the moderators.
2. This one is just technicalities/nit picking, but it isn't really a health meter, is it? Health meters start of filled and then drain as you take hits. This meter starts off empty and fills as you take hits. Maybe change it so it starts off as a full green bar, draining but staying green as you get warnings, then changing yellow and red as you get more and more moderations until it's empty and you're banned. Or just change the name to something else. Like I said, this is really nitpicky.
