You're right, interpretation is key. Saying someone "sells fakes" infers that the bulk of what they do is move fakes. I think that's a bit misleading. I'm certain I have a fake or two in my collection. Does that mean I "buy fakes"? No, not to me. 2 out of 700 or whatever doesn't mean I "buy fakes." If your baseline is to say that every single person with a collection that's bought from someone other than Nike "buys fakes", we can just disagree. Do I think at some point Zadeh sold some fake pairs? Of course, it's a numbers game. Do I think the bulk of what we was moving was fakes? No, it doesn't seem that way from what people that actually bought from him said.
If you want to be weird about it, you can say FootLocker, Champs, Finishline, etc all "sell fakes" bc I guarantee you they've taken fakes in on exchange or return and turned around and sold them.
