I got also negativ feedback for nothing and one for a rule which doesnt exist and you said youself its ok for you.
Are you telling me negative feedback should only be given to people who break the rules? Then in that case, spamming would warrant negative feedback and scams wouldn't. If we're going by that logic. 
So why are you upset if i use the trustfeedback the same way ?
"Because you are doing it, I can do it as well" is not a good argument.
