There is ambiguity between the terms 'users' and 'accounts', particularly if a reader understands a 'user' as a unique individual. A single user may have several accounts, indeed there are some with several thousand accounts. Plankton may form 98% of the accounts, it's not clear that they form 98% of users.
That's not to say that there isn't high churn, but some method of determining the proportion of accounts that belong to the same users in each category is required for clarity.
It may not be possible to identify multiple accounts by logic here. We may have to do it manually.
Statistical methods might be possible. Sampling accounts, using a manual process to find multi-account users and extrapolating the numbers based on the sample.
Yes, but we may need more manual power and the result might not be worth the effort. Let the professional organisations do that if steemit becomes the next Facebook and they want to write about this network's bot problem!
Eventually the reward pool should make it financially worthwhile, but not now.
Yes, Agree.
