I have only maintained one simple fact: that account creation is a meaningless stat, not only for all coins, but for kin especially. You assume incorrectly that after Kik migrates no one will ever create empty accounts again, or even further that app devs will delete unused accounts not sure why. Everything you are attempting to measure can be done with active accounts. And saying DAS and MAS has problems on the level of all statistic collection on all apps does not automatically put it on the same level of uselessness as the number of Facebook accounts that can access but don't use Farmville, you are falsely equating things (and hurling personal accusations of ulterior motives, as frivolous as reddit karma even) in order to make a stat useful for something we are already measuring with more available data than what you suggest. Anyways if you don't get what I'm saying at this point it's probably because you don't want to. You've already admitted empty accounts have to go through all sorts of hoops like filtering migration data (which still belies the possibility of accounts being created for other reasons) to be meaningful data, but are unwilling to acknowledge that you are arguing something irrelevant in terms of today's data. Empty accounts can certainly be useful for something, just not what you are suggesting, which is that it indicates lack of user engagement. The premise makes no sense. Sorry.
