I always know who reps me, benefit of being a gold member.
Don't think mods/admin really like people talking about it and really there isn't much point. The odd neg rep like that doesn't really hurt as they are coming from people with no rep power. Just don't piss off high rep posters like admins etc, have good posts and your rep will go up. I actually like getting negged so I can go in and see that it dropped like 5 points lol.
