I see that cited feedback but I suppose it is clearly an abuse of power to prevent me from scamming someone you should have at least leave a neutral feedback not a red one like what you do on my wall KWH oh how I remember those times.
A red feedback is like saying I'm going to scam someone :-D however if it is truly necessary I wouldn't argue anymore.
Neutrals are RARELY seen or paid any attention to.
Abuse of "power"? Don't think so.
As for my Neutral, it was left sometime after you left yours, once I viewed you feedback to and from others. Like I said, it's pretty much crap feedback from you.
Making a thread about this will do nothing, you must resolve it with the one that left it. Trust is not moderated.
