I don't get this. A instamine is not a premine. The devs did not preemptively take a large number of coins out of circulation. I wonder if money changed hands here to get us listed as such. Shame on coinmarketcap, shame on the Monero shills/devs.
I have to say I did not tell them it was a premine. I told them it was an instamine (and even that was only extra supporting information such as quotes from Evan after someone else had already posted about the instamine itself). You can find my post on their thread (it was linked here). That's the only communication I've had with them at all. Personally I think they should change the tag to "significantly premined or instamined" (and I said that too on their thread) but that is just my opinion. What they do is up to them.
