Rambotnic is an idiot, and he was also caught trying to squeeze money out of someone who thought he was being scammed, and in addition he borderline-plagiarized some content but didn't get banned. You can safely ignore his feedback, because that's pretty much what everyone else is going to do.
By the way, if you're going to start tagging people like V-Power for what I see as an iffy reason (maybe you can explain, but I don't see how he was trying to scam), expect to get retaliatory negs and negs from other people as well. I've found that when you give someone a neg and they don't agree with it, sometimes they'll give you negative feedback from every single one of their alt accounts. Not saying this is what happened in the case of V-Power/Rambotnic, but that's kinda how it looks.
None of that feedback is trusted, so again you don't really have to worry about it. Some of the most prolific scam-taggers have mountains of retaliatory feedback, which might be considered a badge of honor.
I am a programmer. There are a lot of newbies in the Services section who do not understand how the trust system works. They may see that moron's feedback against me and not trust me.
Perhaps the staff can lookup his IP address so I can take legal proceedings against them.
