My thoughts:

Instamine is entirely subjective - what emission curve constitutes the "insta" aka how do you define "instant" because that means literally "in one moment"?  do you include coins that ever changed block reward - manually or by fast algos? community knowledge / involvement / voting?  Mistake by dev or premeditated?  Dev "instamined" 95% personally or his cat jumped on the keyboard and killed his miner and he got 0.1% and who else got what?  Positions of the stars and planets at the moment of launch?

Premine is entirely objective - pre-mine has a clear *literal* definition: coins solo-mined by the dev before the launch date, easy to *prove* by anyone with a BCT link and blockexplorer.

And the *reason* for marking coins as such is to warn investors of a potential *distribution problem* - which can be for a 1000 reasons throughout the coin's life and is often impossible to know objectively, and requires a hell of a lot of on-going work by CMC to get right - and why?  So Monero can get definitions changed that have been working fine for CMC & it's users, to be more inline with their agenda?  

Thanks Gliss, I uses CMC everyday because I trust your data and it's well presented / easy to use, not someone's subjective opinion on what is good or not - thanks for keeping your impartiality.
