As for AliExpress rejecting a claim due to lack of evidence, maybe we should put together some instructions for proving there is a fake.
The easiest is the relabeled c6: the STM Demonstrator says it's got 32k flash and I assume one can just send a screenshot of that.
I suspect the other fakes can be identified via processor timings. E.g., here: https://github.com/rogerclarkmelbourne/ ... -569760423
I also noticed that my last fake reported 128k flash in the Demonstrator, instead of the 64k that the genuine parts so (even when they have 128k), but we shouldn't use that as evidence as AliExpress will think "why are you complaining that it has more memory?!"
