I don't know what it matters if it is 4 months or 14. I had 1 particular month where I could pretty much prove they were lying - as much as it is provable - but you didn't really seem to care. I strongly believe one single month is enough if you prove someone is lying. I did with screenshots and detailed trade lists. They failed to prove the opposite. If that didn't matter I don't think 200 months of results would.
I have emails in which I asked them about results, I asked 2 of my friends from different countries to pretend they want to join and ask them about their results, they failed to respond properly, they were just b*llsh*tting. I have those emails, too, in case you are interested...
As I said earlier, I never expected a proper sentence on them, because obviously my point can not be proven beyond a certain point. All I was hoping that you would put a note on their review page stating the facts what you already know. That they were accused, then asked to prove themselves, but they didn't do anything. That would help people to make an informed decision.
