I just took a look at Foxpup's trust page, and the above image doesn't look like it's from his. You might want to clarify that unless I'm missing something obvious.
Lots of feedbacks are left without any trading having occurred between members. Obviously there's abuse that happens, but trusted members, DT or otherwise, usually leave negs to warn the community of unsavory members--and there's nothing wrong with that, as long as the feedback is true. The neg you got from Foxpup was because he thinks you're an alt of spy100. I don't know if that's true or not, but then you go on to this "Lauda gang" thing, which doesn't exist.
Nor is Foxpup trying to scam anyone, so you've got that wrong as well. If you think he is, you need to back that up with some hard evidence.
Edit: Ah, that screenshot is of Foxpup's
received feedback. What relevance does that have to your accusation?
