Moderators do not remove feedback.
In your case, all your feedback is untrusted, which means you don't show negative trust.
In short, nothing you can do, so don't worry about it.
Okay thanks for your explaining. I will not wory anymore about any untrusted feedback from any scammer.
Why don't you have the power/access to do that? It is obvious that is a scammer that gave me neg trust.
you may give him a negative rating in return for yours, explaining why he is wrong (as reference you may link to this thread).
but as Vod said: you shouldnt worry about it.
negative rates (esp from from untrusted members) are not important. anybody should read through the trust ratings anyway
